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-jpeg-dir=/usr/local \
--with-png-dir=/usr/local/ \

--with-pspell=/usr/local \
--with-curl=/usr/local \
--with-xml \

--enable-ftp \
--enable-gd-native-tt \
--enable-gd-imgstrttf \
--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 \
--server-uid=www \
--server-gid=www \
--libexecdir=/var/www/modules \
--enable-module=rewrite \
--enable-module=so \
--enable-shared=speling \
--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.
------------------------------------------------------------------------
[2001-10-21 18:28:34] [EMAIL PROTECTED]
I can't reproduce this with PHP 4.1.0Rc1 and GD 1.8.4.
Which GD version do you have?

With this code (via Rasmus/php-general):
<http://www.php.net/~rasmus/reductor.php>
<html>
<body bgcolor="#000000">
<font color=#ffffff>Original Image:</font><img src="php.png" align=middle><br
clear=left>
<?php
if(!$ch) $ch='$';
$im = ImageCreateFromPNG('./php.png');
$output = " ";
for($y=0;$y<imagesy($im);$y++) {
for($x=0;$x<imagesx($im);$x++) {
$color = ImageColorsForIndex($im,ImageColorAt($im, $x, $y));
echo "<font size=\"1\" color=\"#";
echo printf("%02x%02x%02x",$color['red'],$color['green'],$color['blue']);
echo "\">$ch</font>";
}
echo "<br>\n";
}
?>
</body></html>
Apache stops responding; Nothing is displayed, not even an error. Apache must be
restarted to bring it back to life.
In the error_log, one sees:
[Sun Oct 21 06:10:03 2001] [notice] child pid 28635 exit signal Segmentation fault
(11)
[Sun Oct 21 06:10:03 2001] [notice] child pid 28634 exit signal Segmentation fault
(11)
Etc...
My php 4.0.6 configure line:

I listed this as graphics related, but I really don't know if it really is.
