First I did a trace with WINEDEBUG=+relay,+seh. I noticed that the last
call before the crash was to QueryPerformanceFrequency. Further the
location of the crash was only a few dozen bytes from the call to this
function, which made it definitely suspect. Disassembling those bytes
showed that the program is expecting something bigger then 1 MHz, while
wine returns the cpu clock in kHz. If you have a clock less then 1 GHz,
then there is a problem.

No idea about this one.
