Crash backtrace

[Matthew Gabeler-Lee]

VLC has been crashing on me a lot lately, very similarly to other
people.  Here's -vvvvvv output (most of it, anyways), and the backtrace.
It looks like something inside the imdctsse is demolishing the stack.
With this hypothesis, using --imdct imdct and it plays nicely again, but
a tiny bit choppy, which I guess is expectable if one is removing ASM
optimizations.
