No feedback was provided. The bug is being suspended because
we assume that you are no longer experiencing the problem.
If this is not the case and you are able to provide the
information that was requested earlier, please do so and
change the status of the bug back to "Re-Opened". Thank you.

There is not enough information to investigate the problem here. 

It is in your best interest to investigate the problem further and attempt to find a way to reproduce the bug.

This is the only way to move forward.

Description:
------------
we are experiencing ranodm segfaults crashes, with different scripts.
Therefore, unfortunately, we have no code to reproduce the crash.

PHP configuration (we're using php-fpm and latest nginx)

'./configure' '--prefix=/usr/local/php-krs-fpm' '--without-pear' '--without-sqlite3' '--without-pdo-sqlite' '--disable-phar' '--disable-fileinfo' '--with-gd' '--with-png-dir' '--with-jpeg-dir' '--with-freetype-dir' '--with-mysqli=mysqlnd' '--with-bz2' '--with-curl' '--enable-mbstring' '--enable-sockets' '--with-zlib' '--disable-simplexml' '--disable-pdo' '--disable-dom' '--enable-fpm' 



Actual result:
--------------
Program terminated with signal 11, Segmentation fault.
