So, having a look at the TAILQ_FOREACH definition, it's going to unpack to:
for (ev = TAILQ_FIRST(&ctx->events);
ev != TALQ_END(&ctx->events);
ev = TAILQ_NEXT(ev, ev_io_next) {
and that's going to turn into:
for (ev = ctx->events.tqh_first;
ev != NULL;
ev = ev->ev_io_next.tqe_next) {
So, given those stack traces, I assume you're using gdb. Start with
ctx->events.tqh_first, then look at the ev_io_next.tqe_next field of
that, then the ev_io_next.tqe_next field of that, etc, until you get a
repeat or a NULL or something that looks crazy.
