Hello,
We are experiencing SIGSEGV with PHP-FPM (v5.4 from Red Hat Software

Here are the details:

Using .gdbinit for v5.4.16 from php-src GitHub repository, I found where
the error is generated, and it is indeed a static call to a method (which
might not be statically defined).
No information there: code error, that is right, but no reason for any
segmentation fault to occur.
I know v5.4.16 is far from being the latest version of the branch,
however, it is being used as shipped by a stable distro, thus believed to
be... stable.
Any idea how to solve the problem?
Thanks,

Well, simply put... 5.4 is NOT a stable branch; it's an old-stable and
currently in security-releases-only-mode until September 14th when it
will reach its end-of-life.
Secondly, 5.4.16 is an OLD version. The most up-to-date version of 5.4
would be 5.4.39. The fact that RedHat ships it as stable does not mean
it IS the latest stable release.
What I would suggest is testing this again, with the latest versions
(5.4.39 and 5.6.7), to see if the problem is still there. If so > post a
bug report at http://bugs.php.net/, if it's gone: well, you know what to
do then :) (upgrade to the latest PHP version...).
