CentOS 5.2 - /usr/sbin/httpd: double free or corruption (!prev) error
Hi List,

We've been seeing the following error on a CentOS 5.2 x86_64 /
2.6.18-92.1.6.el5 install (from /var/log/httpd/error):

*** glibc detected *** /usr/sbin/httpd: double free or corruption (!
prev): 0x00002ad8ebed2d80 ***
[Thu Jul 10 19:12:19 2008] [notice] child pid 5261 exit signal
Segmentation fault (11)
[Thu Jul 10 19:12:48 2008] [notice] child pid 12180 exit signal
Segmentation fault (11)


The following packages are installed:

If we remove the php-pdo / php-mysql packages, then the crashes stop.
But, we need those packages, so that's not a solution.

Any ideas as to what might be causing this?

We've tried the obvious things; the only thing that's not "vanilla"
here are a few settings in /etc/php.ini (having to do with max
execution time and max memory). The php code that's being run does
have its share of php warn/notices:

PHP Notice: Undefined index: d in [snip] on line 1699
PHP Notice: Undefined index: verbose in [snip] on line 1819
PHP Warning: Invalid argument supplied for foreach() in [snip] on
line 1695

So I would not be surprised if it is tickling something out of the
ordinary, but it should still not be causing a segfault!

Any thoughts as to what's going on here, and how to fix it? I'm
tempted to install php 5.2.6 from utterramblings repo, to see if that
works around this.
