Description:
------------
PHP crashes in case of warning messages during MINIT().
In case of warning messages during MINIT() the php_log_err() function
is called. In case error_log directive is set to log errors into file
this function tries to add timestamp using formatting through
php_format_date(). However it leads PHP into infinity recursion if TZ
isn't set, because php_format_date() throws another warning.
Even preventing the recursion with static flag makes PHP crash in
ext/date because of uninitialized DATEG(tzcache).
