I may have found the bug. I just debugged some unrelated Amiga stuff andnoticed weird FPU related crash that only happened in more compatible/cemodes.

FBcc instructions don't fully reload instruction prefetch pipeline whenthey branch. I forgot that some FPU instructions can change PC withoutcausing exception...


Patch coming soon.
