Hi,

In one of our tests, we saw a race condition on event_debug_mode_too_late. We are using 2.0.21 stable.

In the test, one thread has on top of the stack

#0 Âevent_assign

#1 Âevent_new

#2 ... omitted

and another is doing

#0 Âevent_add_internal

#1 Âevent_add

#2 Â... omitted

Setting macro _EVENT_DISABLE_DEBUG_MODE fixes the problem.Â

A google search shows this might be similar to reports here:

and here:

Thanks.
