Hey,
I can reproduce it, below is some backtrace with debug symbols and source
and hopefully a few useful notes. Sorry: no patch attached ;)
(gdb) bt

(gdb) print base
$3 = (struct event_base *) 0x0
It seems like a (nul) pointer dereference.
It seems because the table is empty in hce.c hce_setup_events() and the event
is not initialized:
if (!(TAILQ_EMPTY(env->sc_tables) ||
event_initialized(&env->sc_ev))) {
evtimer_set(&env->sc_ev, hce_launch_checks, env);
bzero(&tv, sizeof(tv));
evtimer_add(&env->sc_ev, &tv);
}
TAILQ_EMPTY(env->sc_tables) is true and the timer is not initialized.
but in hce.c hce_launch_checks() the timer is used:
evtimer_add(&env->sc_ev, &tv);
My test config (/etc/relayd.conf):
table <service> { 127.0.0.1 }
http protocol "t" {
tcp { nodelay }
}
relay "r" {
listen on "127.0.0.1" port 80
protocol "t"
forward to <service> port 8080
}
I hope this helps.
