Your issue probably isn't related to this one, could you maybe open a new bug?
It would also be nice if you could attach a short reproduce script, otherwise
it's very hard to guess what is going on ;)

Hi ... we currently reproduced the segfault in the same line (zend_gc.c - "pz =
*(zval**)p->pData;":
- PHP 5.4.7
- Very long running and memory intensive command line script
- Always reproducable
GDB-Backtrace:
Program terminated with signal 11, Segmentation fault.
