While playing around with correct values of the
dl.RTLD_xxxx flags in the dl module, I found that I
could crash python as follows:

python -v
[...]
>>> import sys; import dl
dlopen("/usr/lib/python2.4/lib-dynload/dlmodule.so", 2);
import dl # dynamically loaded from
/usr/lib/python2.4/lib-dynload/dlmodule.so
>>> sys.setdlopenflags(15)
>>> import ascend
# ascend.pyc matches ascend.py
import ascend # precompiled from ascend.pyc
dlopen("./_ascend.so", f);
python: Objects/stringobject.c:105:
PyString_FromString: Assertion `str != ((void *)0)' failed.
Aborted

Thanks!

I don't have ascend.so.  I  tried importing time and it
crashed hard.  I checked in a fix for me.  Let me know if it
doesn't fix the problem for you.

Hi Neal,

Yeah the ascend.so thing is something I'm working on with
SWIG, basically some bindings for ASCEND, see
http://pye.dyndns.org/ascend/.

I'm probably not going to check out and build python from
sources, so I'll just have to take your word for it ;-)

Cheers
JP
