OK, we have our suspect then: some kind of backward incompatibility
between gdb-6.x (which is sync'ed with gcc-3.x) and the objects compiled by
gcc-2.x, and it is most likely to be caused by either a change in the
name-mangling relating to the new C++ ABI in series 3 gcc, or a change in
the debug info format.

I'm not too familiar with the internals here, so my first recommendation
to both of you would be to revert to a 5.x gdb, which was the contemporary
version to 2.95, and as Fabian has already observed seems to handle the
object files in question without any problem.

cheers,
