At the place [[debugging/GDB]] looks for debugging symbols by default (`/usr/lib/debug/lib/`), Debian's `libc0.3-dbg` stores only the frame unwind information used for backtracing. If you want to step into glibc while debugging, you need to add `LD_LIBRARY_PATH=/usr/lib/debug` to debugged program's environment (`set env VAR value` from the GDB command line). If that still does not work, try `LD_PRELOAD=/usr/lib/debug/libc.so.0.3` instead.
