[mapserver-users] PHPMapscript, Ming & Segmentation fault.

Wed Sep 8 14:24:25 EDT 2010

Hi,

I'd say that php mapscript is not the cause. Could you try to display your map 
using the CGI directly. If you get the same seg fault error, it would be good 
if you could create a ticket with a minimal test case with a mapfile and data 
(perhaps you could do a simple ogr2gr from postgis to shapefile).

regards,
Alan
