Bug #64635 [NEW]: segfault in inmem_seek_to_tz_position from parse_tz.c

From: shakaran at gmail dot com Operating system: Centos 5.9 PHP version: 5.3.24 Package: Apache2 related Bug Type: Bug Bug description:segfault in inmem_seek_to_tz_position from parse_tz.c Description: ------------ I am using cPanel with cpeasyapache and php 5.3.23. I get a apache core file when Xcache and eAccelerator are loaded at same time, because in the error trace, php try to guess the timezone in error_log. Then it produces a segfault. I start gdb in the core file showing this: # gdb /usr/local/apache/bin/httpd core.21552 GNU gdb (GDB) CentOS (7.0.1-45.el5.centos) Copyright (C) 2009 Free Software Foundation, Inc.
