The problem I'm running into is the php_cgi!main() on PHP5.4 has changed
behavior. The php_cgi!main() function is seeing us return a
ZEND_HANDLE_STREAM,

is a (php_stream*), when in fact it's php_wincache's (fcache_handle *).
It then attempts to access the php_stream.ops (a v-table-ish struct),
which is not in the fcache_handle, and it jumps off into an invalid
address and
promptly AV's.

I think you should contact Dmitry, as he was the one that committed
r301058. That code looks very strange. It seems to want to break the
abstraction of zend_stream and assume that handle stores a php_stream (to
use e.g. zend_stream_getc instead of php_stream_getc).
But I don't think the assumption done to break the abstraction is correct.
For instance, see
http://lxr.php.net/opengrok/xref/PHP_TRUNK/ext/phar/phar.c#3364
which has:
file_handle->handle.stream.handle = phar;
and *phar is of type phar_archive_data, which is not a php_stream (or an
augmentation thereof).
