Old Status: Open
Status: Bogus
Bug Type: GD related
Operating System: Linux - SuSE 7.2
PHP Version: 4.0.6 and 4.2.0-dev
New Comment:
The bug clearly is in either the gd library or png library
and not in PHP -> Bogus.
Please report this to the gd/png library authors.

Rebulding gd-1.8.4 with libpng-1.0.12 then rebuilding PHP 4.2.0-dev corrected the
problem. Apache no longer segfaults.
However, it *says* TTF is disabled in gd:
% egrep -i truetype ~root/php_configure.log
checking whether to enable truetype string function in gd... no
But a call to <?php imagettftext(); ?> (with no arguments) *does* give me:
Warning: Wrong parameter count for imagettftext() in /var/www/htdocs/ttf.test.php on
line 3
And phpinfo() says:
FreeType Support: enabled
FreeType Linkage: with freetype
T1Lib Support: enabled
So is that be anything to worry about?
But I suppose that doesn't matter as far as the bug report. If it's anything to worry
about, just let me know privately if you want.
For the record, the working configure(s):
PHP 4.2.0-dev
% ./configure \
--with-config-file-path=/var/www/conf \
--enable-debug \
--with-gd=/usr/local \

Thank you! :) You guys are great!

The segfault seems to be happening in the png code.
I guess the 1.2.0 version might not be very stable.
Try with the previous release, 1.0.12.
I will check this out myself too.

No such luck.
% uname -a
Linux callisto 2.4.12-4GB #1 Fri Oct 19 08:34:54 GMT 2001 i686 unknown
Still SuSE 7.2..
PHP 4.2.0-dev:
% ./configure \
--with-config-file-path=/var/www/conf \
--with-gd=/usr/local \
--with-tiff-dir=../tiff-v3.5.6-beta \

--with-freetype-dir=/usr/local/include/freetype2 \
--with-apache=../apache_1.3.22 > ~root/php_configure.log
I excluded DOM this time because of failed deps in 4.2.0-dev with libxml
% cd ../apache_1.3.22
% SSL_BASE=/usr/include/openssl
% ./configure \
--prefix=/var/www \
--mandir=/usr/local/man \

--enable-module=ssl \
--activate-module=src/modules/php4/libphp4.a \
--activate-module=src/modules/perl/libperl.a
% cp src/httpd /var/www/bin/httpd
Started https (SSL) and accessed the same script and got the segfault 11 again.
Suggestions? I swear gd is the devil.
------------------------------------------------------------------------

Same version.
% ls /usr/local/src/graphics
T1Lib-1.2 freetype-2.0.4 gd-1.8.4 jpeg-6b libpng-1.2.0
I'm still testing; I was tired as $#!t last night and I had to give it up. So I guess
this may be directly related to graphics after all?
For the record, I also tested without mod_ssl and without mod_perl as well. Still
segfaulted.
I'm about to try 4.0.8-dev from snaps and see if that makes any difference.
