That's fixed now, try again with latest git.

Thanks, back to the original issue in wine 1.1.13.

Can I do anything else?

This is your friendly reminder that there has been no bug activity for 6
months. Is this still an issue in current (1.1.33 or newer) wine?

Still current in wine 1.2-rc7

Installation works without issue now.

But running the main program causes the Unhandled page fault

No it does not, this bug is for TMG version 4.0d, which is no longer available
from the website, if it ever was?

If you are interested in testing TMG4 I can provide the installation files
(without the serial number, which is not needed to trigger this bug) email me
directly.

For the first crash:

What happens is that the application tries to resize a memory block, but the
DPMI_xrealloc helper calls DPMI_xalloc and assumes success in the block resize
case. The application passes an extremely large allocation size (around 2 GB),
so DPMI_xalloc fails and DPMI_xrealloc blindly uses the returned NULL pointer.
Making xrealloc recognize this condition seems to fix the crash.

For the next problem:

fixme:int31:DPMI_xalloc failed to allocate linearly growing memory (2148921344
bytes), using non-linear growing...
fixme:int31:DPMI_xalloc failed to allocate any memory of 2148921344 bytes!

bytes), using non-linear growing...
fixme:int31:DPMI_xalloc failed to allocate any memory of 2148102144 bytes!
...

For some reason, the application uses the queried DPMI free memory information
to try to allocate all available memory, and it spends a huge amount of time
doing this until it crashes. Hacking DPMI_xalloc to reject allocation sizes
larger than 512 MB (or some reasonable arbitrary value) gets the application to
start. Perhaps the DPMI free memory information needs some hard limits for
applications like this one. There are many more issues after this, but that
would seem to belong in another bug report.

Thanks Andrew, I can confirm that your patch in wine 1.3.0 fixes the "Unhandled
page fault on write access"

Should I open a bug report for the second issue you mention? How do I hack
DPMI_xalloc to reject allocation sizes larger than 512 MB? I gather you made it
to the serial entry screen?

Thank you
Nat

Yes, please open a new bug report. As for hacking DPMI_xalloc, just add a check
that makes DPMI_xalloc bail out when the requested size is above a certain
specified value. The Master Genealogist interface didn't appear terribly
usable, so I wasn't sure what I was looking at.
