That doesn't seem to work for me:

  nickrob/47 src/gdb/gdb -q myprog
  Using host libthread_db library "/lib/tls/libthread_db.so.1".
  (gdb) info line
  No line number information available.
  (gdb) info source
  No current source file.

I do "list main" but that doesn't work for languages lik Ada.

The same could be said for -stack-list-frames and backtrace, 
-stack-list-locals and "info locals" etc.
