I don't know much about ip2k but for sparc and pa-risc fp is the old sp.
If fp = sp+10 then fp+10 is the old fp. It looks like the +10 is done twice
perhaps at your chages and somewhere else but unfortunately I'm not a 
gdb developer ...
Do you know where (in which cpp file) the backtrace functionality is?
(I've programmed it for sparc solaris and intel linux and try to do it
 for pa-risc hp-ux, but on hp-ux the most things seems to be a little bit
 more complicated ...)
