[Bug 36638] valgrind shows a definite leak in wininet/tests/http.c

--- Comment #1 from Bruno Jesus  ---
I can't find this =/ The callstack shows that an async call is queued [1] and
when the call is triggered it always frees the memory [2]. The only possible
thing I see is if the async call is not triggered after being queued.
