New Comment:
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.

Please try using this CVS snapshot:

For Windows:

I can't reproduce it using 5.2.7CVS.
