New submission from Maciej Fijalkowski:
The bug is a little tricky to reproduce. You need a 32bit linux. First compile x.c with:
gcc -O3 -g -shared -o x.so x.c -std=c99 -msse3 -ftree-vectorize -mfpmath=sse
and run x.py. It segfaults because the alignment of stack is not preserved (and it's assumed on a modern linux). Patch attached.
