Sorry, yes you need either set gdb-show-main or gdb-many-windows to t, so gdb 
displays the source file. I think gdb by default only shows the comint buffer, 
you need to set gdb-show-main to get the 2-window layout.

Recipe:
- emacs -q
- (setq gdb-many-windows t) / or (setq gdb-show-main t)
- maximize frame
- M-x gdb
- make room for source window. Make the source window span the whole width of 
Emacs frame works for both layout.
- step until gdb steps into a function in another file
