that code helps a lot. A standard gcc (no flags) of that code breaks, but if you compile it with gcc -m64, you can address large memory spaces.
So I will try and compile numpy with -m64....
It won't work. Your Python is not compiled as a 64-bit program. The whole stack down to the runtime libraries needs to be built as a 64-bit program. That's easy enough to do with a single-file C program, but in Tiger the 64-bit runtime provides very few services, not enough to build Python.
