IE6: Help Engine Sputtering, Main Engine Doesn't Start, Segmentation Fault
At the outset I must apologize for the length of this post. This situation is intricately convoluted and, currently, I cannot interpret the information that I have collected. Right now I can only relay information that I think is relevant. I would be more than happy to generate more info, but I will need some specific direction for commands and so forth. Right now I have reached the limit of my current troubleshooting skills. My overall goal is to get Edit Studio 4, a video editing application, running in wine. It depends on the IE6 Help Engine. There are other situations with this app and that's why I don't depend on an older version of wine to run it. Right now, if I can't get IE6 to run its help engine, I can't get my app to work. Here goes on my problems with IE6. Conventions: 1013 implies wine compiled from the cvs update on October 13 and a .wine, created from that update aug implies wine version compiled from the cvs update on October 13 and a .wine from a wine version, compiled from my repository, before the 20040824 16:00:16 CDT commit Symptoms: 1. with wine from 1013 and .wine from 1013, IE6 exits with no window--this started sometime after the September snapshot 2. with wine from 1013, any version of wine that I compile, and .wine from aug, IE6 runs and Help works 3. with wine from September snapshot and .wine from 1013, IE6 creates a segmentation fault My original symptom was that I couldn't get IE6 Help to work after the September snapshot. I did a regression and identified the commit of 20040824 16:00:16 CDT as causing the problem. The commit edits this patch: http://cvs.winehq.org/patch.py?id=13475 Among other things this patch changes wine/dlls/Makefile.in wine/configure.ac wine/configure it also changes itss.dll. However, my symptoms still persist whether I use a native or builtin version of itss. I include this information because I don't know if the symptoms are separate problems or are related. I am not able to pin point the cause of Symptom 1 because I do not yet know how to update my repository to do a regression. I must wait for the archive after the October snapshot. I have reasoned, since I can get IE6 to work completely using a ~/.wine created before that August commit, that the problem lies somewhere in the "fake windows" directory. There are differences in the registry, win.ini and system.ini files, but I do not know how to diagnose them. The following excerpt, from one of the logs I created, shows that there is a completely different sequence, between the working and non-working situations, when shell32 loads for the first time: trace:loaddll:load_dll Loaded module L"c:\\windows\\system\\shell32.dll" : builtin -trace:loaddll:MODULE_FlushModrefs Unloaded module L"c:\\windows\\system\\shell32.dll" : builtin -trace:loaddll:load_dll Loaded module L"c:\\windows\\system\\shell32.dll" : builtin trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\ole32.dll" : native trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\BROWSEUI.dll" : native err:shell:ReadCabinetState Initializing shell cabinet settings trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\browselc.dll" : native -trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\RPCRT4.DLL" : native +trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\shdoclc.dll" : native +err:rebar:REBAR_WindowProc unknown msg 200b wp=00000000 lp=71180f00 +trace:loaddll:load_dll Loaded module L"c:\\windows\\system\\uxtheme.dll" : builtin +trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\RPCRT4.dll" : native +trace:loaddll:load_dll Loaded module L"c:\\windows\\system\\lz32.dll" : builtin +trace:loaddll:load_dll Loaded module L"c:\\windows\\system\\version.dll" : builtin +trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\urlmon.dll" : native trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\MSOSS.dll" : native trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\CRYPT32.dll" : native trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\OLEAUT32.dll" : native trace:loaddll:load_dll Loaded module L"C:\\windows\\system\\WININET.dll" : native I stopped the excerpt here because this is the point at which the non-working situation exits. I have generated a log from +relay "grepped" for shell32 but do not know how to interpret it to see if I can glean any more information. This log and all the others are contained in the tarball that I have attached. It creates a directory called "wine-trouble" and contains all the information that I have generated. The README contains specifics of what I have done. As I was composing the README for inclusion here, I realized that I had not done two things. I forgot to copy shell and shell32 to my fake windows directory so that all of my tests were conducted with builtin shell and shell32. Additionally, I have not run wine compiled before the August commit with a fake windows created on October 13. I will do both of these and see if I get differenet results. I'm really interested in resolving this and would rather that I had been able to supply better information. However, my knowlege of winedbg, windows and cvs does not currently allow me to proceed further. If anyone wants me to do more, I would appreciate being pointed in the right direction, but I will need some specifics. I have found no documentation on any of the wine mailing lists or other forums to indicate that anyone else is having this problem. It could be something that I am doing. This is why I haven't yet submitted a bug report. If a bug report would be more appropriate, I will do that. Thanks, Dan
I have discovered that IE6 gives a page fault, a first chance exception, when re-creating "Symptom 1" below. I have attaced the output of winedbg. I am unable to interpret this file. As I said before, if anyone wants me to do some troubleshooting or "patch testing," I will be more than happy to do it. Dan McGhee wrote:

I have recreated this symptom with a wine updated from cvs this morning.
