commit 1739a0b8bc1253786fb557e08eb18a277b5673eb
Author: Michael Albinus <michael.albinus <at> gmx.de>
Date:   Tue Apr 22 12:52:08 2014 +0200

So what triggered the crash? is p a NULL pointer?

I don't know. Does this answers ?

(gdb) p p
$1 = (struct mem_node *) 0x0

Yes, this is a NULL pointer.  I hope GC Gods will look into this.

I hope too, because with the info we have, I think only an Oracle or
a God will be of help.  And no, my crystal ball won't help either: it
seems to suffer from Alzheimer of something.

I still have the gdb session open, if it helps.

That crash was the third one in a series of three crashes (I reported
the first as bug#17322 ; the second one I didn't report). Then it didn't
crash for a few hours, then I decided to rebuild and had no such
problems since then. Perhaps we can blame it on a faulty build and close
the bug.

I'll do that, since it seems no-one can do anything with the available
info in any case. But thanks for the reports.
