Summary: test_anydbm segmentation fault

Initial Comment:
After building 2.5rc1 and bfore installing, make test
failed for me at test_anydbm:

cholla 88% uname -a

cholla 90% ./python ./Lib/test/test_anydbm.py
Segmentation fault

I tracked this to Lib/bsddb/__init__.py, line 355, in
_openDBEnv(): e.set_lk_detect(db.DB_LOCK_DEFAULT) See
the attached pdb text output, if it's useful.

Yes, correct.  4.2.52 is the version of the C BSD DB
library.  That's a fairly old version.  I believe the bug is
in there.  If you update to 4.3.x or 4.4.x, I suspect the
problem will go away.

I know very little about bsddb.  The code looks quite
simple.  Assigning Greg as he's probably the only one that
has a chance of knowing.

Excuse my ignorance, but I'm not sure how to determine the
version. Poking around gives me:

cholla 92% ./python
Python 2.5c1 (r25c1:51305, Aug 21 2006, 11:30:37)
[GCC 3.4.5 20051201 (Red Hat 3.4.5-2)] on linux2
Type "help", "copyright", "credits" or "license" for more
information.
>>> import bsddb
>>> bsddb.__version__
'4.4.5'
>>> bsddb._bsddb.version()
(4, 2, 52)
>>>

Is it the second?

I'm guessing this is an old version of berkeley db.  What
version of bdb are you using?
