Ah, actually I can reproduce it with "emacs -Q":

  (1) start a gdb session in emacs, and hit a breakpoint or something so
      that gdb pops up the source in another window (splitting the frame)

  (2) Switch to the source window with "C-x o"

  (3) Delete the other [*gud...*] window with "C-x 1"

  (4) Switch back to the *gud...* buffer using "C-x b *gud...* RET"

  (5) Try to pop up the source buffer again using a gdb command, e.g.,
      just "frame RET".

*bang*, *gdb...* buffer disappears, source buffer is only ting
displayed... :-(
