I notice that you have used --with-gd both when compiling PHP and Mapserver.

Actually, you should use something like --with-gd=/usr when compiling
PHP. Otherwise PHP gets compiled with it's bundled version of GD, and
php_mapscript.so gets compiled with whatever version of GD is found at
build time. If these versions don't match exactly, nasty things can happen.

Substitute the real path where GD is installed instead of /usr, of course.

To be really sure, use the same path when compiling Mapserver. If you
have only one version of GD installed on your system, it shouldn't
matter, but better safe than sorry.

This seems a likely indication of conflicting GD versions between PHP
and Mapserver.
