Bug description:Segmentation fault on ZTS Embed SAPI

Description:
------------
PHP 7 is current stable
PHP 7 is build as a static library

./configure '--disable-fpm' '--disable-cgi' '--disable-cli'
'--enable-embed=static' '--enable-maintainer-zts' '--without-iconv'

g++ --version
> Apple LLVM version 7.0.2 (clang-700.1.81)
> Target: x86_64-apple-darwin15.2.0
> Thread model: posix

I build a simple example to demonstrate the threading problem. 
On OS X the example crashes within a second. 

Sourcecode: https://gist.github.com/paresy/b4babb919a86e9764bc4

Copy crash.cpp into your php7 folder.
Compile with: g++ crash.cpp -Imain -Itsrm -Izend -I. --std=c++11 -Llibs
-lphp7 -lxml2 -lresolv

empty.php:
<?

Start it. It should crash. :-)

PS: PHP 5.5 and probably 5.6 is affected as well.

Expected result:
----------------
No crash. Endless loop doing the work. 

Actual result:
--------------
Segmentation fault: 11

and a lot of warnings which make no real sense:
<b>Fatal error</b>:  Maximum execution time of 30 seconds exceeded in
<b>Unknown</b> on line <b>0</b><br />
