This bug has been present since before the time that commit f8a519 (Dec 2008) tried to make the dispatch loop re-entrant. Dereferencing eventLoop.handles outside the lock risks crashing, since any other thread could have reallocated the array in the meantime. It's a narrow race window, however, and one that would have most likely resulted in passing bogus data to the callback rather than actually causing a segv, which is probably why it has gone undetected this long. * daemon/event.c (virEventDispatchHandles): Cache data while inside the lock, as the array might be reallocated once outside.
