Do you have a complete disassembly of the function it crashed in and register
dump at the point of crash? That would help.

Since 0x296318e8 is data, we need to investigate where we jumped.
The backtrace looks normal, so I think you're getting anomalous jumps when
optimizing long_richcompare.

So the difference seems to be only the -fPIC option? Can you get the
preprocessed .i file with -save-temps ?
