Hi,
I tried to run the debug remote program with gdb via ssh. I followed the
instructions from the [[info:tramp#Remote processes][info:tramp#Remote
processes]]:
,----
| 5.5.5 Running a debugger on a remote host
| -----------------------------------------
|
| ‘gud.el’ provides a unified interface to symbolic debuggers (*note
| (emacs)Debuggers::). TRAMP can run debug on remote hosts by calling
| ‘gdb’ with a remote file name:
|
| M-x gdb <RET>
| Run gdb (like this): gdb -i=mi /ssh:host:~/myprog <RET>
`----
However, after the program to debug is read, it looks like there is some
error setting up gdb's inferior tty?

I tested it with `-Q' by building the latest emacs in the git:
GNU Emacs 28.0.50 (build 1, x86_64-apple-darwin18.7.0, NS appkit-1671.60
Version 10.14.6 (Build 18G6032)) of 2020-10-22

Pushed to both the emacs-27 and master branch. Closing the bug.
I don't know whether there will be an Emacs 27.3, but it doesn't hurt to
push the fix, I believe.
Best regards, Michael.
