try to make full PHP rebuild (make clean; make install)
In case it doesn't fix the problem, I need a reproduce case anyway (or at least
an ability to analyse crash dump on a remote system).

Description:
------------
Segfault that happens since revision 318671 (Fixing #60139).
Test script:
---------------
For now, I can only repeat this with phpunit if putting 4-5 tests together, not
a single test script is able to reproduce it.
I can take some time if it is really required.
Expected result:
----------------
No segfault :)
Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
