I think you're on the correct track.  In every case where I've ever
seen that message (or one like it), it's because the symbol has been
optimized away by the compiler.

Note that just because you're using `-ggdb' doesn't mean that the
compiler isn't doing some optimization.  It depends on the compiler, but
it's likely the compiler is still doing "-O2".  Try changing CXXFLAGS to

        CXXFLAGS='-ggdb -O0'

possibly with other flags (turn off inlining, etc), depending on the
compiler.
