bug#57968: 29.0.50; Emacs crashes in console, when invoked from mutt

[Jean Louis]

I use mutt to send emails, but normally emacsclient. This time Emacs
server was busy, and I have invoked settings in mutt:

:set editor="emacs -Q -nw"

to use it from console.

But then when editing, Emacs crashes:

$ mutt

These addresses can only be interpreted on your system, and are
otherwise useless.  So either you translate them to file names and
line numbers using the technique described in the node "Crashing" of
the user manual, or you need to arrange Emacs to run under a debugger
and post the backtrace from there.

Btw, this part:

> emacs(+0x48334)[0x5596d6d3d334]gency escape.

hints that Emacs attempted the "emergency escape" feature, for some
reason (did you press C-g more than once or twice?).  If so, then this
abort was triggered by you.

I'm also wondering whether "emacs -nw" can be run from mutt, since
mutt is (AFAIK) full-screen text-mode application, and so it probably
usurps the terminal and doesn't allow other programs work in
full-screen mode, something that Emacs must do.

So perhaps the scenario was like this:

  . you invoked the editor
  . emacs couldn't display on the terminal and seemed to freeze
  . you typed C-g several times
  . emacs performed the "emergency escape" procedure and aborted
    itself

Sounds plausible?
