PHP-FPM segmentation faults in 5.6

[Pzz]

Hi,

First of all; if this message is missplaced at this forum feel free to move it!

The problem: I get segmentation faults. I tried to dump and debug (there's a first time for everything) and got the following result:

Core was generated by `php-fpm: pool esther                         '.
Program terminated with signal 11, Segmentation fault.

(I coloured the line which I think is the main problem)

I didin't try to get more debuginfo yet because I found the next threat that seems to be "alike" https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=754432.

I found some info on changing symlinks to get around this problem, but I've got no clue.


CentOS 7 - PHP 5.6.3 - DA 1.46.3 - CB 2.0

You could try disabling opcache, or applying https://github.com/manuelm/php-src/commit/1b742a2e9f73c3ae57fbe7939932e22b619ce65e.patch patch for PHP.

The patch is part of 5.6.4 of last Friday and the update in CB 2.0 did the rest. Problem solved.

Thanks!
