[php-maint] Bug#543177: /usr/bin/php5: random segfault running moodle cron job

Package: php5-cli
Version: 5.2.10.dfsg.1-2
Severity: normal
File: /usr/bin/php5
I noticed a php core file in my corefiles directory. It appears it was
running the moodle cron job at the time:
Core was generated by `/usr/bin/php -f /usr/share/moodle/admin/cron.php'.
It is not reproducible, the cron job runs every five minutes and this is
the only segfault that occurred. If the below backtrace is not useful,
please just close this bug.
