Summary: Python is dumping core after the test test_ctypes
Initial Comment:
Hi ,
Iam building Python-2.5 on HPUX Itanium. The
compilation is done without any error, but while
testing the same using gmake test it is dumping core
telling "Segementation Fault" after the test
test_ctypes. Please help me in resolving the above
issue.Iam attaching the output of gmake test.
Thanks in advance,

This is the code that crashes:
from ctypes import *
print cast(c_void_p(0), POINTER(c_int))

You will need to run Python in a debugger and find out where
it crashes.
