[geos-devel] Segfault under apache 2.2.9/python/ctypes

Hey folks,

Bit of a cross-post, but this has shown up in a couple of places now across
a few people, so I thought i'd fish for ideas here too...

GeoDjango (http://geodjango.org) has python+ctypes wrappers around the C
interface for GEOS. Under Apache 2.2.9 (eg. Ubuntu Intrepid), mod-python and
mod-wsgi reproducibly segfault when interacting with GEOS geometries. The
same code works fine under the python shell or via fastcgi, as does other
ctypes code.

modwsgi list: Segfault under modwsgi but not shell
http://groups.google.co.nz/group/modwsgi/browse_thread/thread/a488d2551c4c7df0

django-users list:  GeoDjango in Ubuntu 8.10, Segmentation Fault
http://groups.google.com/group/django-users/browse_frm/thread/e337057e9df9bb9

I'd appreciate any insight anyone can offer.

Thanks,

Rob :)
