New Comment:
AFAIK only be using a non-stack based evaluator (pcre_dfa_exec)...
which is not compatible with the perl regular expressions, see the
description at

I understand it is a known pcre behavior but does that mean it is ok to
let pcre trigger a segmentation fault? Is there no possible way to
handle this failure gracefully?

That is known PCRE behavior.
See: http://manpages.courier-mta.org/htmlman3/pcrestack.3.html

In my case the parens were unnecessary so I removed them which stopped
the Seg Fault.
Is there a way to handle this error from inside php?
If I set pcre.backtrack_limit to any other value will it always seg
fault if it is too low?

Setting pcre.backtrack_limit = 10000 prevents the crash for me.
