Let me point out that you can run inside of gdb with

target record

and that allows you to step backwards from the point of the core dump.
This can be extremely helpful for finding the point in execution where
things start to go wrong.  Recording, of course, slows the execution
speed quite down, so it sometimes helps to find a suitable place for a
breakpoint where you switch on "target record".

It's a nuisance that I can't reproduce on my 32bit system.  Maybe I need
to see what it would entail to install a 64bit system in addition (my
CPU would allow that).
