Description:
------------
Both TS and NTS crash. On a debug build VS gives the following error:

Unhandled exception at 0x102D369E (php5ts_debug.dll) in php.exe: 0xC0000005: Access violation reading location 0x5A5A5A56.

and the debugger stops in zend_execute.h:337 (second line in zend_vm_stack_clear_multiple()). 

Here is the corresponding BT:
