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/
