Porting Corosync/Pacemaker - Help needed with gdb

[Stephan <stephanwib%googlemail.com@localhost>]

Hi folks,

some time ago I managed to get Corosync working on NetBSD - now the official 1.x builds can be compiled and run "out of the box". Recently, I made Pacemaker 1.1 and cluster_glue compile after making some cosmetic changes to the code.

However, when I load the Pacemaker subsystem into Corosync, corosync crashes with SIGSEGV. It alway does in pthread_mutex_lock(), for example in the following code block:

===========
static int ipc_thread_active (void *conn)
{
        struct conn_info *conn_info = (struct conn_info *)conn;
        int retval = 0;


        pthread_mutex_lock (&conn_info->mutex);                                   <<<--- CRASH
        if (conn_info->state == CONN_STATE_THREAD_ACTIVE) {
                retval = 1;
        }
        pthread_mutex_unlock (&conn_info->mutex);
        return (retval);
}
==================

I am not sure how to track this down with gdb. Here are some findings:

=================

=====================

Has anobody an idea how to proceed?
