Description:
------------
I have PHP 5.4.4-14+deb7u9 (cli) (built: Apr 18 2014 14:34:31) on my server and i want use DateTimeImmutable, so i created my «DateTimeImmutable» class which extend «DateTime». 

I overload all public methods to add «clone» on $this object. 

To be sure my class work properly i executed tests date_time_immutable.phpt (https://github.com/php/php-src/blob/94e15ff3877f842e5eb5c89e3aeab214fb4a3a33/ext/date/tests/date_time_immutable.phpt) 


But when i run it i have «Seg fault error».
