That's what happens when pd (or whatever process being debugged) is 
already crashed.

That's a sign that it was trying to kill itself with signal 6 (ABORT).

And it's because of a memory error that you ought to debug with Valgrind.

You told me that it crashed with such a memory error, and that's why I 
told you to make a report based on Valgrind in the first place. You didn't 
tell me about hanging (freezing). In the case of an actual freeze, you use 
GDB with Ctrl+c. If pd freezes while trying to abort... I don't know why 
that could happen, but fixing the abort will fix the freeze.
