I have some rather large examples using structs. However this small example
still blows.

Yes, this is the technique I have tried. Also, I have seen other code examples similar to yours.

arrow:~/home/python/pyrex/bomb$ make
pyrexc -I/usr/include/python2.2 bomber.pyx
gcc -I. -I/usr/include/python2.2 -g  -c bomber.c 
ld -shared -o bomber.so bomber.o -lc -lm 
python -c "import bomber"
EOF
make: *** [bomber.so] Segmentation fault
make: *** Deleting file `bomber.so'
arrow:~/home/python/pyrex/bomb$ 

Bye,

Simon.
