Can you give a clue as to what code is required to cause this crash? Kind of hard to investigate with no clue how to reproduce the problem.

Also:

> NTS
> libgomp.so.1
> libpthread.so.0

You appear to be running the non-thread safe version of PHP with two libraries that use threads. 

Has this ever worked for you on other versions of PHP.
