That's because Emacs already exited by that time.  You need to catch
the moment when it crashes.

The problem here is that you run the wrong program under the debugger:
runemacs.exe.  You need to invoke emacs.exe instead.

Please invoke Emacs under GDB like this:

 gdb c:/Programme/GNU/Emacs/bin/emacs.exe
 (gdb) run -Q --eval=... <put here the rest of the command line>
