Subject: Persistent core dump with python and pthreads-1_60_beta4_1


Hi, I'm trying to get pthreads-1_60_beta4_1 working on both Solaris 2.4
and BSDI 4.4 lite.  I seem to be getting the same probem on both, and
I was wondering if you could take a look at the trace and give me some
idea of how to track this down.  The following is from a gdb trace
of a core dump of a python test:

/build/Python-1.3>./python 
Segmentation Fault (core dumped)

/build/Python-1.3>gdb python core

If you could give me some hints as to where to look, I'd appreciate it.


Thanks.
