[2009-06-11 13:11:42] ak at pre-secure dot de I was able to reproduce the Problem with the current release. It occurs if you try to open an image with an crc error.

[2008-10-31 13:20:03] ak at pre-secure dot de 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.

[2008-10-30 16:49:23] crrodriguez at opensuse dot org memory usage is constant for me, are you sure you are using version 5.2.6 ? [2008-10-30 16:42:03] ak at pre-secure dot de Description: When trying to create an image from a file and an error occures PHP will lose some memory.
