Details - gdImageCreateFromPng, and possibly other image file loaders, makes an assumption that gdNewFileCtx returns a valid pointer, but a review of the underlying code suggests it can return NULL if allocation fails. While it is rare to run out of memory when such little is used, it can still happen. I am reporting this because its bad to assume that the memory returned from any allocation function is valid, especially in C.
