Description:
------------
This bug reproduct on 5.6.39 too. I use apache 2.4 (mod_proxy) + php-fpm. When php-fpm report like this:

- not only one script can do this, bat always "Allowed memory size" error before mass segfault
- I can't disable opcache, because x4 LA on production servers
- can't reproduce, only race condition
- if segfault run with mass error (response code 500+), our monitoring try hard restart, and i can't debug all cases, but if can, I try exec opcache_reset() by php script, and it is work.
- I try increase opcache.log_verbosity_level to 3, and write script to do opcache_compile_file(), buy log file, but cannot reproduce. When this script return error, I extend my opcache black list. Script from top (database_mysql.php) already been there.
- On normal load, with low level bad response code, I infinity have 1 segfault on 3-7 minutes, until restart or flush opcache.
- can't disable Zend Memory Manager, after this action, I can get phpinfo, but our project not working.
- On release 5.6.39 I rebuild php from src (src rpm from remi):
   1. Cannot rebuild debug version, because not all modules src rpm in remi repos
   2. When rebuild with -fsanitize=address, many memory error in php -i (for example). I run many test with valgrind. I understand what I have moor memory leak (curl.so for example), but this is not interesting in my cases. My problem is mass segfault (11 signal).
- one server in production environment build from sources with optflags: x86_64 -O0 -fPIC -g -ggdb2. Only one server gather coredump. All core segfault on low level memory operation (zend_alloc.c for example) or MAKE_STD_ZVAL macros.
- "zend_mm_heap corrupted" on php-fpm log, when bug shoot.

I think my problem like this:

https://bugs.php.net/bug.php?id=71135

This is my heavy pain. Is last comment by first link(?id=64297) treats me?

-Status: Open +Status: Wont fix
 [2019-01-16 09:51 UTC] nikic@php.net
PHP 5.6 is no longer supported. Some issues related to memory limit errors have been fixed in later versions. If this issue still reproduces in PHP 7.2, we can reopen this.
