Description:
------------
I've looked through other similar bugs, but haven't found the exact match. However the main thing is the same: a crash inside zend_mm_alloc_small() when a rather large code base is used/ Trying to extract the offending stuff seems impossible as even the count of retured from a database rows is relevant. (In my case it is distinct: the difference between a crash and a non-crash lays between n and n+1 returned rows from the db.) Thus all I have is two backtraces.

Actual result:
--------------
1) This one is using a plus operator with arrays:
Program received signal SIGSEGV, Segmentation fault.

Using php -n and loading only required extensions (tokenizer, pdo, pdo_pgsql) still leads to the crash.

Any ideas on how to mitigate this crash are welcome too, for this crash only appeared after deploying the scripts in question to a production Linux-server, while there were no crashes during development on Windows [using PHP 7.2.12 (cli) (built: Nov  8 2018 05:47:36) ( ZTS MSVC15 (Visual C++ 2017) x64 )].

Just tested the same code on Windows with PHP 7.2.12 for the sake of it, and it does crash too, while PHP 7.1.21 works fine.

@profic: Can you please rerun valgrind, but with the USE_ZEND_ALLOC=0 environment variable set?
