[php-maint] Bug#493045: Bug#493045: Segmentation Fault in cron console PHP Job

Hello Raphael,

thx for the quick reply and sorry for the late response.

I attached one of the modules which causes the problem. It uses the
mktime and the time function. The checkAuthDB.conf file which gets included
just carries the config array with the localhost mysql connect

Version of libmysqlclient15off is 5.0.51a-11

See my other comments below.

I can not reproduce it means that I did not find a way where the error
appears every single time.

The answers to these questions are stated above.

I will do that this weekend and report then.
