Bug description:  pcrelib broken with php 4.4.5

Description:
------------
Recent update to php 4.4.5 broke PCRE regex support.
The issue showed up upgrading to 4.4.5 installed as apache module (1.3.37
both on 2.4 and 2.6 kernels) and was resolved downgrading back to 4.4.4

I could trigger a segfault with several applications but I was not able to
detect the chunk of php code responsible of it.

Actual result:
--------------
segfault...

#0  match (eptr=0x0, ecode=0x0, offset_top=0, md=0x0, ims=0, eptrb=0x0,
flags=0, rdepth=0)
    at /sources/php-4.4.5/ext/pcre/pcrelib/pcre_exec.c:517
