Core dumps building Python on AIX

The AIX builds fail in the phase where it's building the extensions
using setup.py:

> case $MAKEFLAGS in \
> *-s*)  CC='gcc' LDSHARED='../python/dist/src/Modules/ld_so_aix gcc -bI:Modules/python.exp' OPT='-DNDEBUG -g -O3 -Wall -Wstrict-prototypes' ./python -E ../python/dist/src/setup.py -q build;; \
> *)  CC='gcc' LDSHARED='../python/dist/src/Modules/ld_so_aix gcc -bI:Modules/python.exp' OPT='-DNDEBUG -g -O3 -Wall -Wstrict-prototypes' ./python -E ../python/dist/src/setup.py build;; \
> esac
> make: *** [sharedmods] Segmentation fault (core dumped)

Can someone with access to the snake farm try to find out what's going
on here?

One suggestion I have is to try to rebuild without -O3.  It seems
Python is dumping core, and a broken optimizer is a likely cause.

(Thanks for the HP fix, BTW!  Again the snake-farm has proved useful --
I've decided that the test had no business trying to open 1000 files
simultaneously, and changed it to 100.)
