Description:
------------
My big php scripts arbitrarily end with such an error: Segmentation fault (core dumped)
The application in which this occurs is very large. It is not possible to download it. To reproduce this bug more compactly it is impossible.

My php.ini is standard.
Configure line:
'./configure'\
    '--enable-debug'\
    '--enable-fpm'\
    '--enable-cli'\

Expected result:
----------------
$ ulimit -c unlimited; php ./yii import 12600

end

Actual result:
--------------
$ ulimit -c unlimited; php ./yii import 12600
