*not* very much tested:

<https://gitlab.com/koral/mem-watchdog.el/-/blob/master/mem-watchdog.el>

You can run an Emacs -Q where you use this to monitor the Emacs you are
working on (hopefully the first one does not crash too).  Note you have
to set the OS to allow for gdb to attach on other processes or run the
Emacs monitor as root.

Hope it helps.
