We should do something more like the attached patch, with or without the gcc warning, I think. We may have smuggled the pointer to finished in slot->finished pointer that survives the current stackframe out of the function in the original code, so that is what we rectify by clearing the member when it has the value we stored. http.c | 3 +++ 1 file changed, 3 insertions(+) diff --git c/http.c w/http.c index 229da4d148..85437b1980 100644 --- c/http.c +++ w/http.c @@ -1367,6 +1367,9 @@ void run_active_slot(struct active_request_slot *slot) select(max_fd+1, &readfds, &writefds, &excfds, &select_timeout); } } + + if (slot->finished == &finished) + slot->finished = NULL; } static void release_active_slot(struct active_request_slot *slot)
