This is the same issue as https://bugs.php.net/bug.php?id=70688. It's
not a bug in PHP, it's a bug in a patch used by your package provider. Could you please report
this to Webtatic?

Rasmus - I'll look into doing a source build shortly and update this.

Unable to reproduce on Debian plus it is valgrind-clean. It sounds like it is related to the
distro-specific patches that I know RedHat/Centos do to support the system tz lib. You could help us
verify that by building from our source on that box and testing a non-modified build.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php
for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Note: I tested it on Ubuntu. I did miss that its only crashing on Centos 7.
