I'm unable to reproduce this bug in Emacs 27 (i.e., in the development
version), so perhaps this has been fixed in the meantime?  Is it
possible for you to download it (from git) and check?

Did you do this on a TTY frame?  The OP specifically says "on tty".

I can reproduce this, starting with "emacs -Q -nw", both
on Emacs 26.2 and on the current master branch.

Thanks,

Thanks, should be fixed now on the master branch.

bug#36613: gdb: error on M-x menu-bar-open

[Dr. Ludwig Meier]

Dear Eli, thanks a lot for your help. The error message is gone ??? but, 
in fact, nothing happens now, no menu.

Is there any information I can give you about that?

Best, Ludwig

That's expected, since the first few items on the menu bar are not
menus, they are a kind of tool-bar buttons.  If you have mouse support
on text-mode frames compiled into Emacs, you can click the mouse on
these "buttons" to invoke their bindings.

If you want to open the first real menu item on the menu bar in the
GUD mode, try "C-u 50 M-x menu-bar-open RET".  The argument is the
column of the first "real" menu item.

OK?
