Bug #16841 Updated: imagepng() segfaults

ID: 16841 Updated by: daniel@pressure.net.nz Reported By: daniel@pressure.net.nz -Status: Feedback +Status: Open Bug Type: GD related Operating System: Linux PHP Version: 4.2.0 New Comment: The simplest configuration I can get it to crash with is: configure --with-zlib --with-gd --with-png-dir=/usr --with-jpeg-dir=/usr --pdflib I'm just building the CGI version because it is easier than doing a 'make install' and restarting the Apache etc, but this bug does affect the Apache DSO build as well. The weird thing is that this works fine with PHP 4.1.2, AND the libpng 1.2.1. It seems to look more and more like this bug is pdflib related. Previous Comments: ------------------------------------------------------------------------ [2002-04-26 09:20:11] mfischer@php.net I couldn't reproduce this either with pdflib from pdflib.com. Can you paste the full configure line of PHP and of pdflib ? ------------------------------------------------------------------------ [2002-04-26 08:34:05] daniel@pressure.net.nz I got it to work ok by removing the --with-pdflib from my configure. There's something over at http://www.pdflib.com/pdflib/patches.html which sounds almost relevant (although it affects TIFF routines). I'm running pdflib 4.0.2 ------------------------------------------------------------------------ [2002-04-26 02:23:04] derick@php.net Not closing yet... ------------------------------------------------------------------------ [2002-04-26 02:21:36] derick@php.net I think this is the same libgd / libpng 1.2 incompability as we saw before. If you downgrade to libpng 1.0.9 it should work fine. Can you try this?

(PHP HEAD and GD-2.0.1) This smells like a local libpng problem to me. The segfault is deep inside libpng. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
