Subject: php5: Segfault due to PHP bug in DateTime functions

Date: Wed, 10 Aug 2011 08:43:02 -0500

Package: php5
Version: 5.2.6.dfsg.1-1+lenny9
Severity: normal

Our Drupal site's cron.php script has been causing segfaults every few days for months now.

>From /var/log/apache2/error.log:
[Sun Aug 07 13:05:13 2011] [notice] child pid 2358 exit signal Segmentation fault (11)

Got a core dump and did a backtrace:
(gdb) bt full
#0  0xb76394f3 in strlen () from /lib/i686/cmov/libc.so.6
No symbol table info available.
#1  0xb685e58d in zif_timezone_name_get () from
/usr/lib/apache2/modules/libphp5.so
No symbol table info available.
#2  0xb6ab4113 in ?? () from /usr/lib/apache2/modules/libphp5.so
No symbol table info available.
#3  0x00000000 in ?? ()
No symbol table info available.

This seems to be the bug causing this:
http://bugs.php.net/bug.php?id=45038

I can reproduce it like this:
$ php -r '$dt = new DateTime(); $dt->setTimezone($dt->getTimezone()); '
Segmentation fault (core dumped)

I tracked down the commits by the PHP developer:
http://svn.php.net/viewvc?view=revision&revision=262279
And I think this:
http://svn.php.net/viewvc?view=revision&revision=262280

Unfortunately they do not apply cleanly.

The subject is wrong (sorry, wrong cut&paste), but the message is
still the same...
