[mapserver-users] Segfaults with MapScript from Python

[Jelmer Baas]

The code isn't all that complex, not much more than three layers with a postgis source and using an ogr_style column. 

I'll do my best to create a stripped-down script and test dataset tomorrow.

I don't see any debugging symbols in there making life a little bit
more difficult.

Is your Python code very complex? Could a useful snippet be posted to a gist?
