Hello
I have segfault at openl2tp 1.8 shutdown.
I can clearly see segfault with new xl2tpd version:
Program terminated with signal 11, Segmentation fault.

The point is:
./usl/usl_pid.c :
/* If a callback is registered, call it now */
if (have_callback && (child->callback != NULL)) {
(*child->callback)(child->arg, child->pid, sig);
}
But you already have destroyed plugin at this point.
