Rich,

Since gdImagePtr is a struct and allocated on the stack, it will be
freed when it goes out of the actual scope.

I think that would be pretty useful.


BTW: I don't really understand your valgrind output. Maybe you have 2
different versions of the gd library out there side by side. The
mapserver core and the mapscript wrapper may use different gd (or crt)
libraries therefore using gdFree doesn't actually free the memory
segment passed by the argument. (I guess)
