I suspect I am hitting the same problem with Python 2.5.2 - see #2344.
Since that (or a similar segfault) is a blocker from getting 2.5.2 in
(which I need for OSX 10.5 64 bit) I would really like to get that
resolved.
William: Can you run the integer.pyx with "-verbose" to see what
crahes in detail?
