Summary: "setdlopenflags" leads to crash upon "import"

Initial Comment:
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

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

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.
