[pkg-wine-party] Bug#766028: wine32 segfault

[Uwe Storbeck]

Hi

This bug is not fixed in wine32 version 1.6.2-17 for me too. Only
wine is affected by the bug, but not wine-development.

I also use the nvidia binary driver.

The nouveau driver does not support my hardware configuration
(2 GPUs with 3 screens), at least the last time I tried it.
People which need Direct3D or OpenGL support in wine usually
play games with it and need the better performance of the nvidia
binary driver. So switching to the nouveau driver is often not
an option.

To narrow down the problem I have tested several wine32 versions.
The bug has been introduced between version 1.6.2-10 and version
1.6.2-11. It is sufficient to downgrade the wine32 package and no
other of the wine packages.

When I understand the package version numbers in Debian correctly
the wine32 package versions 1.6.2-10 and 1.6.2-11 are produced
from the same upstream sources. So the bug has been introduced in
the Debian part of the wine32 package between version 1.6.2-10
and version 1.6.2-11. That should considerably narrow things
down.

It's also suspect that wine does not segfault when I run it
inside of gdb. Maybe something in the build process of the
wine32 package has changed between these two versions and causes
the problem.

When I run wine32 in gdb the process gets a signal SIGUSR1 in
wine32 version 1.6.2-11 which I don't see in version 1.6.2-10:

  Program received signal SIGUSR1, User defined signal 1.

The gdb logs for both versions are attached below.

I don't know why this signal has been introduced and what it's
used for, but it may cause the segfault when it's not caught
properly.

I hope this helps a bit to narrow down this bug.

Regards

Uwe
