(You can of course use an audiogen compiled with gcc.)
That disappears if you either:
Compile audiogen with -O0 or -O1, or
Compile audiogen with any processor optimization (--cpu=pentium3, pentium4 or
core2): You should do this anyway, because it's the only way some audio
reference tests pass (probably floating point differences), and it - hopefully -
produces faster code.
I reported this problem to Intel.

FFV1 crashes on all input, I reported this to Michael, but not to Intel (how can
I produce a minimal testcase?), here is my report, unfortunately, Michaels hack
doesn't help anymore:

I removed ffv1 from my testsuite, knowing it doesn't work:
