0. emacs -Q
1. Eval: (tmm-prompt (mouse-buffer-menu-keymap))
2. Select a menu item with the mouse click
from the *Completions* buffer
3. It fails with this backtrace:
Debugger entered--Lisp error: (error "Empty menu reached")
error("Empty menu reached")
tmm-prompt((keymap "Select Buffer" [("*scratch* * " . #f(compiled-function ()
(interactive nil) #<bytecode...
tmm-prompt((keymap (Select\ Buffer "Select Buffer" keymap ...
(progn (tmm-prompt (mouse-buffer-menu-keymap)))
eval((progn (tmm-prompt (mouse-buffer-menu-keymap))) t)
elisp--eval-last-sexp((4))
eval-last-sexp((4))
funcall-interactively(eval-last-sexp (4))
call-interactively(eval-last-sexp nil nil)
command-execute(eval-last-sexp)
This regression began to occur after merging native-compilation.
It seems the problem is that tmm-get-keymap does very strange things:
(cond ((if (listp elt)
(or (keymapp elt) (eq (car elt) 'lambda))
(and (symbolp elt) (fboundp elt)))
I don't know why it checks for 'lambda' and 'symbolp',
but such checks fail on a compiled function.
