Hi all,
I tried to run corosync again on NetBSD 6 BETA. The build errors are
the same, and also it does nothing than utilizing 100% CPU. Luckily,
gdb works in live mode with threads now, and shows this:

As you can see, it jumps somewhere in libpthread from the
corosync_timer_add_duration() function, resulting in an infinite loop.
As a hack, I just commented everything out:
int corosync_timer_add_duration (
unsigned long long nanosec_duration,
void *data,
void (*timer_fn) (void *data),
timer_handle *handle)
{
/*
int res;
int unlock;
if (pthread_equal (pthread_self(), expiry_thread) != 0) {
unlock = 0;
} else {
unlock = 1;
pthread_mutex_lock (&timer_mutex);
}
res = timerlist_add_duration (
&timers_timerlist,
timer_fn,
data,
nanosec_duration,
handle);
if (unlock) {
pthread_mutex_unlock (&timer_mutex);
}
pthread_kill (expiry_thread, SIGUSR1);
return (res);
*/
return 0;
}
Doing this, the corosync service successfully starts and interacts
with its control tools.
Does anybody have an idea what could be wrong with the code obove?
Stephan
