This one (bug 71289) seems to be about crashes involving GC messages
and resizing the terminal.
I don't know the root cause; it could be some bug in the redisplay code.
I started thinking about other redisplay bugs and filed bug#71343, but
that one isn't related to this bug because it's not about GC. The
other 2 issues I mentioned may or not be related, I don't know.

In all reports I'm using TTY frames, i.e. Emacs compiled without X
support; it's not GUI frames.  But I'm running them inside a urxvt
window in X with a window manager.  I wanted a simpler and smaller
Emacs without any X support, but I still run it in X.

Killing frames is not involved or necessary for the current bug report (#71289).
