Package: wine32
Version: 1.6.2-11
Severity: normal

Dear Maintainer,

Running a win32 program which require OpenGL/Direct3D using wine32
will cause segmentation fault happen. This program may be a game
require Direct3D, a testing OpenGL program which only display OpenGL
information, or dxdiag.exe which is a DirectX deagnostic tool
distributed in Debian libwine package.

As dxdiag.exe is common, I use it to discuss below.

With 1.6.2-8, 1.6.2-10 wine32, running below command will not cause
SegFault and GL version can got from wine debug messages:
   $ WINEDEBUG=+wgl wine32 dxdiag.exe 2> wine.log
   $ grep "GL version" wine.log
   trace:wgl:X11DRV_WineGL_InitOpenglInfo GL version             :
3.3.0 NVIDIA 340.46.

With 1.6.2-11, 1.6.2-12 wine32, running the same command will cause SegFault:
   $ WINEDEBUG=+wgl wine32 dxdiag.exe 2> wine.log
   Segmentation fault
   $ cat wine.log
   Wine cannot find the ncurses library (libncurses.so.5).
   fixme:wbemprox:wbem_services_CreateInstanceEnum unsupported flags 0x00000030
   fixme:wbemprox:enum_class_object_Next timeout not supported

Let core can be dumped when SegFault happen, then using gdb I found:
   $ gdb wine32 core
   Program terminated with signal SIGSEGV, Segmentation fault.
   #0  0x7de8ee0a in ?? () from /usr/lib/i386-linux-gnu/libGL.so.1

/usr/lib/i386-linux-gnu/libGL.so.1 is finally soft link to
/usr/lib/i386-linux-gnu/nvidia/current/libGL.so.340.46 which is
provide by libgl1-nvidia-glx:i386 package.

Next I try strace and found something interesting. The same above
command will NOT cause SegFault even with 1.6.2-11, 1.6.2-12 wine32:
   $ WINEDEBUG=+wgl strace -f -o strace.log wine32 dxdiag.exe 2> wine.log
   $ grep "GL version" wine.log trace:wgl:X11DRV_WineGL_InitOpenglInfo
GL version             : 3.3.0 NVIDIA 340.46.

It is something wrong with wine32? Though from changelog, it seems
like no change in i386 when upgrade from 1.6.2-10 to 1.6.2-11.

Some other information:
 change version of libwine have no effect on whether SegFault happen or not.
 wine64 1.6.2-12 will NOT cause SegFault. Other version of wine64 not tested.
 Lastest libgl1-nvidia-glx:i386 upgrade is earlier than wine32
upgrade, so I have not try different libgl1-nvidia-glx:i386 version.
Version of libgl1-nvidia-glx:i386 is 340.46-1, as it is not shown
 My video card is GeForce G 105M/PCIe/SSE2.
