i just stumbled across a weird bug, that segfaults Pd:
when an abstraction with a signal-outlet that is connected to another signal-object get's deleted due to an undo, Pd crashes.

while this sounds complicated, it is not really: just start editing your patch with audio on, make a change to an abstraction, think better and undo: kaboom!

attached patch illustrates the problem.
