Note:  the command line switch 'blacknull' passed to Conquer.exe allows you to
run the executable directly, else it requires that you run play.exe, which
calls autopatch and then conquer.  The results are the same when run from
play.exe.  See my comments in the AppDB entry too.  Please let me know if
debugging output will help.

Could you please try with sound disabled if that works try with alsa instead of
oss.

Just in case its a sound related problem.

Tried all audio options (alsa, oss, nas) and disabled also with Driver
Emulation checked as well.  Same results.

Thanks for getting on this so quickly.

The latest and greatest Visual C++ Runtime, available at:
http://www.microsoft.com/downloads/details.aspx?familyid=200B2FD9-AE1A-4A14-...
doesn't break it any more or less.  Apparently all that is needed is the two
libs mentioned in the AppDB..btw...those can be obtained from that package.  I
noticed lots of 'unknown' return values from mcf42.xxx in the debug output so I
figured an update couldn't hurt. :-)  Yeah right...I'll delete and reinstall. 
FYI, No change to md5sums for those two libs.

If you mean errors like:
0009:CALL MFC42.765(<unknown, check return>(0x110000,00000002,00000040):
returning 0x1d633f8
) ret=00401730
0009:RET  MFC42.765() retval=00000000 ret=00401730

Those are a red herring.  It just means that the parameters to the function are
unknown by the relay/snoop mechanism until the function returns because of the
calling convention.  (If you don't know what that means, just ignore.)

The problem is an uninitialized variable somewhere or another.  From the log,
the first seh entry is:
0009:trace:seh:raise_exception code=c0000005 flags=0 addr=0x4383e0
0009:trace:seh:raise_exception  info[0]=00000000
0009:trace:seh:raise_exception  info[1]=55555555
0009:trace:seh:raise_exception  eax=00000000 ebx=00000000 ecx=55555555
edx=00000029 esi=01d5f5f4 edi=7e77e8b0

c0000005 is an access violation, and ecx has the bogus value: 0x55555555. 
Microsoft uses that value for uninitialized variables in debug versions of
their libraries to help you catch bugs.  This could well be an app bug that
happens not to occur on Windows.

Those are benign and can be safely ignored...no problem.

So, if I understand correctly, assuming your analysis is correct (and I have no
reason to suspect otherwise), there is pretty much nothing that can be done
from the wine developers' POV.

Also, I don't understand the scope. Is that from the Microsoft libraries or is
it definitely limited to the Conquer executable or c3 library (or elsewhere)? 
Is it even possible to tell from the debug output?  If the latter, we just have
to sit on it and hope that the application vendor fixes a compile time warning
that will most likely never cause an error in windows?  Could it also be
related to a missing support file of some sort?  I do recall that they had
changed fonts quite a bit recently, but those are usually benign IMLE, and are
usually included in the patch anyway.  Actually that was back around the mid
4340s that they were toying with the fonts IIRC (before the problem surfaced). 
Anyway, the question stands valid as is.

Not that they'll be very receptive to a bug report for wine anyway, but I can't
go pleading to them without at least a basic understanding of the problem.

Thank you very much for your time on this Juan, and if you need anything
further from me, I'll be happy to supply y'all with it.

FYI.  I did respond to TQD ([e-mail]) but have not received a
response from them.  A second message was sent today.  Ignoring the obvious,
I'm not sure that this bug should be active for now as the error is triggered
by a problem in the binary.  However, (the obvious part) this error is handled,
or is simply not triggered in a real windows environment, so I am unsure what
to do with it.  I'd suggest leaving it open with a back-burner status for now,
but I'll bow to the wine developers' decision.  If it's left, I'll test and
nudge it when I have the time to spare.  BTW, can anyone at least confirm it
before Priority/Severity is changed?  Shouldn't take more than a half hour on a
fast PC with a decent internet connection.

Another wine user (for now, unnamed without permission) contacted me about this
issue which prompted me to contact TQ again.  Looks like we might get some help
from the developer after all.  We now have an interested developer on the TQ
payroll. :-)  The other user has been conversing with a support guy and I've
been on the CC list.  For now the 55555555 is gone, but the access violation
persists.  The interested TQ programmer has requested a backtrace for his
review.  The same error is now confirmed on 0.9.52.  I'm getting a GL error
with .53...52 should be fininshed building in about 10 minutes.  If no GL error
with .52, I'll post a +seh here for review.

I managed to bring up the game login screen with the following steps:
1. Copy the game folder in Windows to ~/Conquer/ ;
2. Copy mfc42.dll and msvcp60.dll to ~/Conquer/ too;
3. Add linux user account to audio group, so audio device will work for WINE;
adduser YOUR_LINUX_ACCOUNT audio
4. logout and relogin linux user account, so that the previous change will take
effect;
5. Go back to home directory to setup WINE configuration:
cd; rm -rf .wine/ ; winecfg
6. In winecfg dialog:
6a. Open "Audio" sheet, a dialog reads "A recommended driver has been selected
for you ." will jump out, click "OK" then. It will setup audio automatically,
click "Apply" button to accept;
6b. Open "Drivers" sheet, my "Drive mappings" setting looks like:
C:      ../drive_c
Z:      /
6c. Open "Graphics" sheet, check "Emulate a virtual desktop", and set Desktop
to "1024 X 768" or larger;
7. Copy cour.ttf (Courier New TrueType font file) and arial.ttf in Windows
Fonts folder to ~/.wine/drive_c/windows/fonts/ folder:
cp /mnt/dos/win/Fonts/cour.ttf ~/.wine/drive_c/windows/fonts/
cp /mnt/dos/win/Fonts/arial.ttf ~/.wine/drive_c/windows/fonts/
Your should change the path in the above commands accordingly.
8. Modify font information in registy file ~/.wine/system.reg, looks like:
[Software\Microsoft\Windows\CurrentVersion\Fonts] 1201379398
"Arial"="arial.ttf"
"Courier"="coure.fon"
"Courier New"="cour.ttf"
[Software\Microsoft\Windows NT\CurrentVersion\Fonts] 1201381146
"Arial"="arial.ttf"
"Courier"="coure.fon"
"Courier New"="cour.ttf"
Remember both places must be modified to add "Arial" and "Courier New";
I guess the reason for the exception problem in WINE is that Conquer has
changed the default font (defined in ini/Font.ini) from "Courier" or "Arial" to
"Courier New", which is not used by WINE as the default setting.
9. Now launch the game:
cd ~/Conquer; wine play.exe

Another reason that may cause exception is that Conquer/debug and Conquer/LOG
folders are not writeable, so do this:
cd ~/Conquer/ ; chmod +w -R debug/ LOG/
If auto patch mechanism is desirable, you probably should make the whole
directory writable:
cd ~/Conquer/ ; chmod +w -R *

I'd like to confirm that adding the fonts allowed me to get to the login
screen.
FYI, I can't see the cursor on the login screen. This may be related to:
  http://bugs.winehq.org/show_bug.cgi?id=6710
it may also be related to the following fixme.
fixme:cursor:CURSORICON_LoadFromFile No support for .ani cursors.

Anyway this is probably a totally different bug.

Is this still an issue in current (1.0-rc5 or newer) wine?

This bug is no longer an issue because it was an access of uninitialized memory
that was fixed in the latest version of the exe.

Conquer Online is still unusable. I don't know whether it technically can be
made to work. Major issues:
1) Wine still lacks animated cursor support (cannot see cursor)
2) Display corruption (cannot see where you are even meant to be clicking)
3) Have to enter text while holding down Alt. More display corruption makes it
hard to see text entered
4) Once I get around all that, I get a "server busy message" and it kicks me.
(This last one is not wine's fault)

Download is no longer available, and the bug is fixed in newer versions. The
other issues are either covered by other bugs, or should have new bugs filed.
