Hi,
Sorry guys but i still have the same pb.
libpng1.2.5 + gd2.0.11 (no fix) + php4.3.0 (Stable).
everything is link with the same libraries :
% ldd /usr/lib/apache/libphp4.so
...
libz.so.1 => /lib/libz.so.1 (0x40284000)
libtiff.so.3 => /usr/lib/libtiff.so.3 (0x40293000)
libpng12.so.0 => /usr/local/lib/libpng12.so.0
(0x402d9000)
libgd.so.2 => /usr/local/lib/libgd.so.2
(0x40345000)
libfreetype.so.6 => /usr/X11R6/lib/libfreetype.so.6
(0x4037d000)
libX11.so.6 => /usr/X11R6/lib/libX11.so.6
(0x403c0000)
libXpm.so.4 => /usr/X11R6/lib/libXpm.so.4
(0x40487000)
libjpeg.so.62 => /usr/lib/libjpeg.so.62
(0x40497000)
...
and
$ ldd /usr/local/lib/libgd.so.2
...
libXpm.so.4 => /usr/X11R6/lib/libXpm.so.4 (0x4004f000)
libX11.so.6 => /usr/X11R6/lib/libX11.so.6
(0x4005f000)
libjpeg.so.62 => /usr/lib/libjpeg.so.62
(0x40126000)
libfreetype.so.6 => /usr/lib/libfreetype.so.6
(0x40148000)
libpng12.so.0 => /usr/local/lib/libpng12.so.0
(0x40190000)
libz.so.1 => /lib/libz.so.1 (0x401c0000)
the back-trace gives..

The fact that both libraries are identical doesn't resolve
this bug..
Here is the buggy script.
<?php
header("Content-type: image/jpeg");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
$im = ImageCreateFromPNG("basn2c16.png");
ImageJPEG($im);
?>

Yup, good idea, reclassifying.

Correct with libpng-1.0.8 as GD and PHP source it works fine...
an entry for the faq?

Forgot..make sure your GD library is linked with the SAME
libpng as PHP is.

I just tried with libpng-1.2.0, latest PHP (4.3.0-dev) and gd 2.0.1
(the 'original' without our fixes) and could not
reproduce this segfault.
Please try the latest (non stable!) snapshot from
http://snaps.php.net/
