Status: Closed
Bug Type: GD related
Operating System: Debian Linux
PHP Version: 4.3.2-RC
New Comment:
I too get Apache segfaults when using the imagettftext function
(scripts do other image things and works fine when not calling
imagettftext - plus have tried many options/fonts in that func with
same results).
PHP Version 4.3.2
Slackware 9
Configure options:
'./configure' '--prefix=/opt/php-4.3.2' '--without-pear'
'--enable-exif' '--with-freetype-dir=/opt/freetype-2.1.4'
'--with-gd=/opt/gd-2.0.15' '--enable-gd-native-ttf'
'--with-mysql=/opt/mysql-3.23.57'
'--with-apxs=/opt/apache-1.3.28/bin/apxs'
I just upgraded to Apache 1.3.28 from .27 but get the same results:
[Wed Aug 20 12:33:30 2003] [notice] child pid 12542 exit signal
Segmentation fault (11)

Segmentation fault (11)
[Wed Aug 20 12:33:45 2003] [notice] child pid 12551 exit signal
Segmentation fault (11)
Note the
[Wed Aug 20 12:33:30 2003] [notice] child pid 12528 exit signal Illegal
instruction (4)
Which appears every 20th line or so. Page after page of segfault
error. I just grabbed the latest versions of Free Type, GD and PHP as
well as Apache but the bug's still there I'm afraid Rasmus.

This bug has been fixed in CVS.
In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.

Works for me now, no more segfaults.

I think I just fixed this issue. The bt doesn't look the same, but the
fact that it only happens on the second request would indicate that it
was getting a bogus cache pointer which is what I fixed. Someone
please verify that this doesn't happen under current CVS.

Note: This happens on the 2nd run on same apache child.
