If the problem is in gud.el, then we must think about the other users
of that code, like "M-x gud-gdb".  gdb-display-source-buffer is
specific to gdb-mi.el.  And I see that as part of your patch you've
removed the test of gud-minor-mode being gdbmi, which is probably not

Also, what happens if the function into which you step is already
displayed in some other window?
