I was able to reproduce the Problem with the current release. It occurs
if you try to open an image with an crc error.

Reproduce code:
---------------
while(true) {
    print "\nMemory: ".memory_get_usage();
    imagecreatefrompng("anyimage.png");
}

Image:

Seems to be fixed with the newest snapshot. Cannot reproduce it
anymore.

I have to admit that my initial bugreport is a litte bit too
unspecific. 

The memory problem only occures if the image is "tainted", f.e. taking
a valid png and change a arbitrary line in the source. 

This will result in an error like this:
PHP Warning:  imagecreatefrompng(): gd-png:  fatal libpng error: IDAT:
CRC error in  ----
and a rapid growth of the memory usage.
