emacs 28.1 causes infinite spawns of emacs processes

[Dov Grobgeld]

Hello,

I'm using Fedora 36 and I just updated emacs through the package
manager and was updated to emacs 28.1. Trying to run the new emacs
causes an infinite loop of emacs processes to be spawned and this goes
on until I either kill them with "killall -9 emacs" or X11 crashes due
to the system running out of resources.

This does not happen if I do "emacs -q --no-site-file" but does happen
if I do "emacs -q".

The emacs window is still responsive when this happens. The last
message shown is: "Loading
/usr/share/emacs/site-lisp/site-start.d/ess-init.el". I can do a C-g
and the last lines of the *Messages* buffer then shows:

Loading /usr/share/emacs/site-lisp/site-start.d/ess-init.el (source)...
Waiting for process to die...done
Quit: (lambda (arg0 &optional arg1) (let ((f #'delete-char)) (funcall
f arg0 arg1))), nil

emacs appears responsive after C-g at this stage, but the emacs
processes keep accumulating in the background and I'm left with no
choice but to do a killall.

I'm running under xorg-x11-server-Xorg-1.20.14 and with the fvwm window manager.

Meanwhile I'm downgrading to emacs 27, but needless to say I'd be
happy to help resolving this.

Thanks in advance!
