Operating system: Windows 10
PHP version:      7.0.2
Package:          Reproducible crash
Bug Type:         Bug
Bug description:Crash in "zend_mm_gc"

Description:
------------
Downloaded Windows PHP 7.0.2 x64 (NTS), Wincache 2.0.0.4 and YAML
2.0.0(RC7)

Website works 20% of the time, the other 80% of the time I get:

Faulting application name: php-cgi.exe, version: 7.0.2.0, time stamp:
0x568d8141
Faulting module name: php7.dll, version: 7.0.2.0, time stamp:
0x568d8c40
Exception code: 0xc0000005
Fault offset: 0x000000000039be3e
Faulting process id: 0xe58
Faulting application start time: 0x01d14cbc989dfd84
Faulting application path: E:\PHP7\php-cgi.exe
Faulting module path: E:\PHP7\php7.dll
Report Id: 4d36902c-9377-4fb8-bb37-890a846cf0a4
Faulting package full name: 
Faulting package-relative application ID: 

In the event-viewer

I've used a 3rd party tool to find the fault address, which seems to be

zend_mm_gc + 6E

so it seems it crashes somewhere in the garbage collector.

With 7.0.0 and 7.0.1 I got 100% crashes and the site never worked.

Site is working perfectly fine in all PHP 5.5 and 5.6 versions.

If need be, I would be open for a remote-desktop session from a trusted
developer to diagnose the problem further.
