[mapserver-users] Segfaults with MapScript from Python

[Jelmer Baas]

Hi List,

Some of my automated renders are failing because Python crashes with an Segmentation fault. I've finally found at least some logs of this:
Feb 12 16:16:19 vm-ctwrender07 kernel: [276759.889265] traps: python[8002] general protection ip:7f104ec4f50f sp:7fff17d8d790 error:0 in libmapserver.so.6.4.1[7f104eb91000+1d8000]

Unfortunatly, I have no idea how to continue. I suspect this has something todo with odd font rendering (too large, too small), since I had issues with that before. Can someone match these addresses with code and find out where it crashes? 

Thanks in advance!

Regards,
Jelmer
