GDB works perfectly well with a program written partially in C, in C++ and in
Ada, at least when you use the gcc compilers (gcc, g++ and gnat).
you can step in all code whatever the language it is written in.
GDB has no specific knowledge about Ada (it has about C and C++) but eventhough
it is possible use it quite efficiently with Ada code, you just have to use
C expressions instead of Ada's. 
We have been using it successfully for more than one year for the GNAT
development which is written in Ada9x and in C.
I have been testing the new GNAT/C++ interface recently and GDB works perfectly
well in this context too...
