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))

***

Also note there are a bunch of errors like this:

Warning: could not import ctypes.test.test_cfuncs:
Unsatisfied code symbol '__divsf3' in load module
'trunk/build/lib.hp-ux-B.11.23-ia64-2.6/_ctypes_test.so'.

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