ogr vrt with php_mapscript

[Olivier Gayte]

Franck,

It has taken some delay because I had never used gdb until now.
You will find herewith the traceback when php_mapscript crashes.
/usr/local/lib/libgdal.so.1 points towards libgdal.so.1.5.0
May I do anything else to help you in your investigation?

Regards.
