[egenix-users] mx-base 2.0.5 segfaults against Python 2.3.3 --without-pymalloc --with-pydebug

[Jacob Smullyan]

This may be already known, but 2.0.5 segfaults *immediately* with
Python 2.3.3 configured --without-pymalloc --with-pydebug on 2 linux
platforms I've tested (gcc 2.95 and 3.3.2).  2.1.0 does not.

From the core backtrace:

etc.  This core was produced simply by importing mx.DateTime.

Cheers,
