I have some perl scripts that aid in finding these sorts of things.
They are geared towards finding which .o produces the unexpected
behavior, and which routine within the .o is the faulty one (this last
one is tuned to gcc on the MIPS, I imagine it could be hacked if
needed for the MIPS compiler).
