segfault. The problem most likely lies with either your specific PHP version or an extension you have installed, you could try to get a backtrace or a core dump to find out exactly where it segfaults. Have you considered moving to PHP7? It is 'the future', after all. It is maturing rapidly and works well on older hardware.
