There is no error either through valgrind.
And yes, the memory usage of PHP MM increases as you keep creating
errors, but the memory is freed when it exits >> no leak.
If you read the valgrind output you pasted here, you will see that it
did not find any error either...

Did you at least try to reproduce it? I tested it on various machines
with the given script and image. It will crash in no time cause it
allocates to much memory.

Run a single pass through valgrind please.

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:
--------------
