Mapserver crashes while antialiasing

Hello Steve,
thanks for the GD-patch.
I've supplied it on both systems. On the SuSE 10.0 box it now works in
both (cgi and moduled) versions.
Within the SuSE 9.2 System there must be another problem. After starting
the application (viewing full extend with road layer only) it produces an
antialised map. If I try to zoom into the map, I got segmentaion faults again.
I'll try to upgrade the System because it's a development system only. So,
I think, it works for me now.
