I've been trying to run wine with a few games, and I've been getting a
similar error and backtrace with all of them. Here's the relevant info:<br>
<blockquote>
<pre>wine: Unhandled page fault on read access to 0x00000000 at address 0xf748c110 (thread 0043), starting debugger...
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0xf748c110).
...
Backtrace:
=>0 0xf748c110 in libc.so.6 (+0x74110) (0x0032e670)
1 0x7e59fae9 X11DRV_WineGL_InitOpenglInfo+0x353() [/home/jb/programs/wine-git/dlls/winex11.drv/opengl.c:351] in winex11 (0x0032e670)
... (goes on for a dozen or so more, not relevant to this bug)
</pre>
</blockquote>
So my first thought was "What's wrong with libc?" Then I looked at the
source of the file at level 1 of the stack and found this:<br>
<blockquote>
<pre>350: str = (const char *) pglGetString(GL_EXTENSIONS);
351: WineGLInfo.glExtensions = HeapAlloc(GetProcessHeap(), 0, strlen(str)+1);
</pre>
