Summary: test_bz2 fails

Initial Comment:
I just did a cvs update and a fresh build of Python
dies with a
segfault immediately after running test_bz2.

build-pydebug> ./python ../Lib/test/regrtest.py
test_bz2 test_grammar
test_bz2
/usr/home/jeremy/src/python/dist/src/Lib/test/test_bz2.py:30:
RuntimeWarning: mktemp is a potential security risk to
your program
  self.filename = tempfile.mktemp("bz2")
test_grammar
Segmentation fault (core dumped)

A partial gdb stack trace shows that it's dying in
PyObject_Malloc().
I'm running with a debug build of Python.  Not sure
what, if anything,
it would do with a release build.
