The code segfaults because you have increased the recursion limit. The
amount of recursions is limited by the stack size. A C program with a
usually stack size can have about 4000 recursions. Python takes at least
two stack levels for each recursion.

The documentation
http://docs.python.org/library/sys.html#sys.setrecursionlimit contains a
warning, too.
