Thank you! Built the development version this morning, but unfortunately 
the same:

$ emacs -q
M-x gdb
Run gdb (like this): gdb -i=mi
M-x toggle-debug-on-error
M-x menu-bar-open

Debugger entered--Lisp error: (wrong-type-argument listp gud-print)
   popup-menu(gud-print (#<window 4 on *gud*> 374 (1 . 0) 0 nil 374 (1 . 
0) nil (0 . 0) (1 . 0)) nil t)
   menu-bar-open()
   funcall-interactively(menu-bar-open)
   call-interactively(menu-bar-open nil nil)
   command-execute(menu-bar-open)
