Is it possible to use ctypes with a shared library which uses MMX/SSE

I getting a seg fault when I hit one of the intrinsics. I'm wondering
if there might be some sort of stack alignment problem.
I am using gcc version 4.2.3 and Python 2.5.2 on Ubuntu 8.04.
Any suggestions would be helpful.
Well, stack alignment would be a problem with how the shared library gets
compiled, nothing to do with ctypes (I think). However, if you are passing in
arrays from ctypes, *they* may also be misaligned. Try to check the addresses of
the ctypes values you are passing in. I'm not entirely sure how to do that, though.
