Can you provide a backtrace so we can identify which instruction is invalid ?
It seems that in the SSE2 code used in the soundtouch library (used
for "stretching" the sound) there are a few SSE3 instructions
incorrectly placed there which would make your processor crash as they
The other possibility is that you recompile without SSE support (it's
a configure option)
