Hi all,

I recently installed 5.4.0 on a CentOS 6.2 box and am now getting segfaults anytime we try to draw a PDF file (with fpdf). My config line is below:

./configure --with-apxs2=/usr/sbin/apxs --enable-cli --enable-exif --enable-mbstring --enable-mbregex --enable-sockets --with-mysql --with-mysqli=/usr/bin/mysql_config --with-pdo-mysql --with-libdir=lib64 --with-zlib --with-gd --with-jpeg-dir=/usr/lib64 --enable-soap --enable-calendar --with-freetype-dir=/usr/lib64 --with-libexpat-dir --enable-ftp --enable-calendar --with-curl

Running gdb on the core dump from apache, I get this:

Any thoughts are appreciated. Thanks!

How recent did you install it?  My initial thought is to disable APC.
The 3.1.10 version released last week fixed a few bugs that caused
crashes with PHP 5.4
http://pecl.php.net/package-changelog.php?package=APC&release=3.1.10
Note this version of APC incorrectly reports itself as 3.1.9
(https://bugs.php.net/bug.php?id=61695)

If this doesn't help, construct a small reproducible testcase and log
a bug at https://bugs.php.net/report.php
Installed it about a week and a half ago. Removing APC did nothing to fix the issue. Bug #61757 filed.

Thanks!
