Hi Ben,

sorry for the late answer, but I finally got some spare time and I found 
a reason for this segfault.

Problem was within opcache module, and actually, problem was that I had 
two files:

/etc/php.d/10-opcache.ini

and

/etc/php.d/opcache.ini


Both files had same content, which is ok. Reason I had these two files 
was that I use puppet as CM, and in 5.6 you guys changed names of the 
ini files by adding enumeration in front of them, and puppet deployed 
this file as usual.


Actually, to reproduce it, it is enough to have:

zend_extension=opcache.so
zend_extension=opcache.so

in /etc/php.ini.


While this is my mistake, I still am puzzled as to why does php segfault 
in this case. IMHO, php should handle multiple .so loading same as 
Apache does, by printing warning and ignoring the second 
'zend_extension=' line...

I already filed a bug upstream, so I'll just update the bug description, 
or open a new bug...

What puzzles me though is that I remember having this problem with early 
5.6.x versions (5.6.3) even with opcache disabled, so I'm kinda really lost.

I'll give it a little bit more testing to see if it's stable enough to 
move prod to 5.6.x now.
