I'm keep on getting crashes. I have sent you a new dump but I have no idea to know whether it
is related to the crashes.
Unhandled exception at 0x74791FFA (php_opcache.dll) in php-cgi.exe.6112.dmp: 0xC0000005: Access

@mrechtold, thanks for the further infos. I'm adding a couple of backtraces here based on your
dumps. However looks like we can't come forward without a reproduce case, sadly. Also changing
to the opcache issue, by at least 2 backtraces it is.
Thanks.

I have several new crash dumps from the latest snap:
Revision: r5aebdc9 (March 08 2015, 14:06:45)
All these crashs happen right when the HTTP server is started. Most likely during init/population of
the opcache.
I have sent the new crash dumps (including the debug symbols) to ab@ and laruence@
