The x86 version quant use stack to store temporary data with movdqa Could you give me your exe file? so I may check the really assembly code. Thanks! GCC builds always set HAVE_ALIGNED_STACK=1 If we need to disable this for Win32, it would not be hard. I've tried to build with HAVE_ALIGNED_STACK=0/1, but I'm getting the same crash.

We should have this fixed soon, though. yes, you're right...I just tried 64-bit version and it works fine.
