No, only the mentioned test fails for me. Newly tested with both TS and NTS snaps from Nov 22th http://windows.php.net/downloads/snaps/php-5.5/
. A way to repro your fails?

Is this the only test that is failing for you?
I just played around with it on Windows and for me anything involving pushed stack arguments
crashes. E.g. the yield_during_function_call test.

Btw. there are no valgrind complains on Linux for this test.

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:
