Comment 2 Jan Kratochvil 2010-10-14 15:17:15 UTC 
Post upstream (in September):
[patch] Fix ELF stale reference [Re: [patch] .gdb_index: Do not crash on NOBITS]
http://sourceware.org/ml/gdb-patches/2010-09/msg00192.html

Many thanks for the "ctrl-c madly" advice, I have seen so far this bug reported by ABRT zillions times, never reproducible!  I was not aware the fix above is useful in the real world.
