why q is null when ast_mutex_lock(&q->lock) ?

   for (q = queues; q; q = q->next) {
       ast_mutex_lock(&q->lock);

Was this an optimized build? did you have any debugging enabled? has this happened again? can you recreate it? what was happening at the time (were you doing a reload)?

Going to close this. No additional information available on a more detail backtrace. Some verbose/debug logging with debug threading enabled would probably also be helpful here to see what else might have been going on. Please re-open if you have more information available.
