No worries. We'll keep this one about the intro movie bug.

I received a private email from someone else about the openal-1.15 bug a while
ago, and their crash looks just like your crash. So I'm fairly confident that's
what gave you that crash. I'll submit that patch very soon, I just need to give
it a little more testing.

Anyway, back to the intro movie problem. The game repeatedly calls
acmStreamOpen trying to convert some audio from WMA to PCM:

0065:trace:msacm:acmStreamOpen ((nil), (nil), 0x506a8f0, 0x50a2ca0, (nil), 0,
0, 5)
0065:trace:msacm:acmStreamOpen src [wFormatTag=353, nChannels=2,
nSamplesPerSec=44100, nAvgBytesPerSec=16005, nBlockAlign=2973,
wBitsPerSample=16, cbSize=10]
0065:trace:msacm:acmStreamOpen dst [wFormatTag=1, nChannels=2,
nSamplesPerSec=96000, nAvgBytesPerSec=192000, nBlockAlign=2, wBitsPerSample=8,
cbSize=0]
0065:trace:msacm:acmStreamOpen => (512)

This continually fails because Wine's msacm32 can't decode WMA audio. I guess
the game has a bug where it doesn't handle this failure gracefully, and
eventually runs out of stack space, causing your freeze/crash.

So, either Wine's msacm32 should support converting WMA to PCM, or we're
somehow misleading this program into thinking that it can do the conversion
when it can't. Writing a test with the same acmStreamOpen call and running it
on Windows would confirm what Windows's msacm32 can do, and tell us what Wine's
should do.
