#18303 [Csd]: PHP crashes when ImagePNG() is used

ID: 18303 User updated by: thx.79@schweiz.org Reported By: thx.79@schweiz.org Status: Closed Bug Type: GD related Operating System: Linux (Kernel 2.4.4-4GB) PHP Version: 4.2.1 New Comment: Ok, final notes on this one: The problem wasn't libpng, zlib or jpeg-6b, it was the PDF-Library!! See also Bug 16841 for a similar case. So before you try to recompile libpng and the other stuff, try (re)compiling the newest version of pdflib... It took me quite a while to figure this all out, so I hope this helps anybody else to save some time. Bye, Thomas Previous Comments: ------------------------------------------------------------------------ [2002-07-23 08:44:27] thx.79@schweiz.org Ok, I deleted /usr/local completely and compiled everything from scratch....and it worked. So it must have been something with the libs or so. Thanks and bye, Thomas ------------------------------------------------------------------------ [2002-07-22 21:32:43] sniper@php.net I'm unable to get PHP to crash when using libpng 1.2.0. You propably had a mixup with the libs. Remove ALL existing libpng* files and recompile libgd using 1.2.x and remember to point PHP configure to the SAME libs with --with-png-dir ------------------------------------------------------------------------ [2002-07-22 21:29:25] thx.79@schweiz.org Ok, you were right. Downgrading to libpng-1.0.14 was the right thing to do. But I still think this is a little bit odd and the problem still seems to be somehow PHP-related, because if I compile GD with libpng-1.2.4 (which crashes in PHP) and then run 'make test', all PNG-Images are generated without _any_ problem at all! And, aren't there any functionalities missing, when I just have the older version of libpng?? Bye, Thomas ------------------------------------------------------------------------ [2002-07-12 08:06:40] sniper@php.net And make sure you really have compiled both PHP and GD with SAME libraries (libpng, zlib..etc.) ------------------------------------------------------------------------ [2002-07-12 07:00:22] sander@php.net I'm using libpng 1.0.12 and I don't have any problems. As Jani (sniper) said on the orginal bugreport, libpng 1.2.x is reported to work badly with libgd. You might try downgrading libpng to 1.0.x. If the problem goes away, then it's probably not a bug in PHP. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
