Higher up the are lots of warning to many files. When I switched to USE="-cpudetection", the compilation succeded. Maybe something is wrong with my CPU (Atom 330), but I think this flag should at least be with warning. I have no idea, what causes the bug; I file the bug just to notify others.

Reproducible: Always

Steps to Reproduce:
1. Set ffmpeg's local USE variable to +cpudetection [I know, I just emphasize with this plus].
2. Wait a couple of minutes.
3. Watch the crash.
Actual Results:  
Compilation stops.

Expected Results:  
Successful compilation of ffmpeg.
