Oops, mailed it to myself instead of the list!
It's been a long day...

I've managed to get a backtrace, attached, thanks to Ross J. Reedstrom's
excellent example from the archives, also attached.
I'm not sure whether the stack frame shown is corrupt, it seems to just
loop over and over again. (I got fed up after 400+ frames)
The final few frames show us asking for more memory, the point at
which things seem to go out of control.

Is this any help?
I'm no expert in gdb, but I can follow instructions. ;-)
Thanks,
Keith.
