Summary: Python 2.3.3 make test core dump on HP-UX11i

Initial Comment:
I built Python-2.3.3 on HP-UX11i in the same way that I 
built Python-2.3.2.

However, this time running 'make test' core dumps on 
the second pass with:

test_sax
*** Termination signal 138

Stop.

The output from test_sax.py is given below. Each test 
appears to fail, but the summary gives zero failures (this 
also happens with Python 2.3.2, but 'make test' doesn't 
core dump on that release).

I have now installed Python-2.3.3 plus PyXML-0.8.3 and the 
core dump in 'make test' has returned.

So, it looks like a compatability problem with PyXML-0.8.3 ?

This is the configure command I used:

base_inst_dir=/opt
python_link=${base_inst_dir}/python

CC=cc OPT="+O2 -z +Onofltacc +ESlit +Oentrysched +Odataprefetch +Onolimit +DA2.0" INSTALL="./install-sh -c" ./configure --with-threads --without-gcc --with-cxx=/opt/aCC/bin/aCC --without-libd --with-cycle-gc --prefix=$python_link --exec-prefix=$python_link

This is exactly the same command I have used on previous 
Python 2.3 releases which did not core dump in 'make test'.

Note it uses the native HP compiler.

I have now just rebuilt without optimisation, using:

CC=cc INSTALL="./install-sh -c" ./configure --with-threads --without-gcc --with-cxx=/opt/aCC/bin/aCC --without-libd --with-cycle-gc --prefix=$python_link --exec-prefix=$python_link

It still core dumps at the same point in the second pass 
of 'make test'.

I have attached a stack trace from the core file. I noticed 
that this has references to /opt/python/lib/python2.3/site-
packages/_xmlplus/parsers/pyexpat.sl.  This is the previous 
installation of Python 2.3.2 plus PyXML-0.8.3.  

I wondered if I had forgotten to reset $PYTHONPATH before 
running 'make test', so I did that and tried again but it still 
core dumped.

So next I reset the symbolic link /opt/python to the empty 
directory /opt/python-2.3.3 and ran 'make test' again. This 
time it didn't core dump!

So why does the test suite access the previous installation 
when PYTHONPATH doesn't include it?

On an HP box I tried, I don't have any problems.
 * HP-UX taylor B.11.00 A 9000/829
 * gcc 3.2

What compiler are you using?  Have you tried on the HP test
drive machines?  Are you compiling with optimization?
