Run a single pass through valgrind please. Previous Comments: ------------------------------------------------------------------------ [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. Reproduce code: --------------- while(true) { print "\nMemory: ".memory_get_usage(); imagecreatefrompng("anyimage.png"); } Image: -------------- http://drahop.de/php/anyimage.png ------------------------------------------------------------------------ [2008-10-31 13:45:59] paj...@php.net not a bug > bogus ------------------------------------------------------------------------ [2008-10-31 13:43:32] ak at pre-secure dot de Seems to be fixed with the newest snapshot. Cannot reproduce it anymore. ------------------------------------------------------------------------ [2008-10-31 13:42:42] paj...@php.net Please provide an example image (link to it or drop me a mail). ------------------------------------------------------------------------ [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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
