Re: Emacs crashed trying to connect to X display

[Richard Stallman]

    If it can't connect to an X server, it just crashes Emacs - that can't be
    the desired behaviour, can it?

I agree.  Your setting of DISPLAY was user error, and I am not sure it
can possibly "work right", but there's no reason it should crash
Emacs.

It looks like setting up the initial terminal calls x_display_ok
to verify that the specified display can be reached.
But it looks like there is no such test when you open a display during
the session.

Does this prevent the crash?
