At the place [[debugging/GDB]] looks for debugging symbols by default (`/usr/lib/debug/lib/`), Debian's `libc0.3-dbg` stores only frame unwind information. If you want to step into glibc while debugging, you need to add `LD\_LIBRARY\_PATH=/usr/lib/debug` to GDB's environment. If that still does not work, try `LD\_PRELOAD=/usr/lib/debug/libc.so.0.3` instead. You can add to GDB's environment via `set env FOO bar` from the GDB command line. It seems that this is no longer needed with the Debian glibc 2.5 packages, but I may as well be wrong. Have to check that again.
