I think there's some magic in gdb for this but I'm not sure how to
make it happen. If you figure it out I would think it would be
generally useful and we should find a way to put it in the source tree
so it works for everyone.
You might find it useful to put breakpoints in heap_deformtuple() with

added to offset, but I find no way to calculate that while I am
dubugging.
I guess you could just add a few macro define lines to your .gdbinit,
