Hi,
When ev_signal is used, the assertion on line 220 fails on
event_base_free(). This is because the signal stuff is not dealloced.
Two solutions: remove that assertion (since the event that is not
removed is static in signal.c, there is no memory leak here) or use the
patch I have attached. The patch I attached also closes the pipe that
evsignal_init opened.
Hmm, ev_signal does not look at which event_base is used. Is that
threadsafe?
Best regards,
Wouter
