  I would _strongly_ recommend moving to gcc-2.3.3. It has a number of bug fixes
over gcc-2.3.2. Also, make sure that libg++-2.3 is rebuilt using gcc-2.3.3. Just
to be complete, I would also rebuild gdb-4.7 with gcc-2.3.3. It is most
difficult to find the problem sometimes when using tools built with different
versions of the compiler.

  I have seen the "`.bf'" errors on and off with different versions of
gcc/libg++/gdb. With my current setup (gcc-2.3.3, libg++-2.3, gdb-4.7) there are
no errors, and I can debug g++ code just fine.

  Good luck.
