Please try that just in case...

I don't think it's related (though it could be). Overall, VORBIS_PSYCHO
isn't tested much, so it's still a bit risky (and improvement has yet to
be properly measured).

Can you try with quality 8 and no VBR?

This looks a bit like something I've seen before. Is that an x86-64
system? I remember someone trying to pinpoint a crash at that place, but
I lost the IRC logs. One other question: how often does the crash occur?
