Summary: os.popen() seg faults on FreeBSD 5 

Initial Comment:
Here is the crash with Python 2.1.1 on my FreeBSD 
5.0-current system:

[ace:culler]$ python
Python 2.1.1 (#5, Aug 18 2001, 17:41:43) 
[GCC 2.95.3 20010315 (release)] on freebsd5
Type "copyright", "credits" or "license" for more
information.
>>> import os
>>> mypipe = os.popen('ls /')
Segmentation fault (core dumped)

No problem occurs when I do the same thing in 
Python 2.0, which was compiled under FreeBSD 4,
but is running here under FreeBSD 5:

[ace:culler]$ python2.0
Python 2.0 (#2, Nov 16 2000, 22:22:48) 
[GCC 2.95.2 19991024 (release)] on freebsd4
Type "copyright", "credits" or "license" for more
information.
>>> import os
>>> mypipe = os.popen('ls /')
>>> mypipe.readlines()

Can't reproduce this on FreeBSD 4.4, either, using the
current CVS.

I can't reproduce this, and I don't have access to a FreeBSD
5 machine. Can you debug this yourself? We'd welcome a
patch.
