Yep, I've got the gcc-12.2.0 natively compiled on this netbook using gcc-11.3.0, after 5+ days + a crash + 5more days.

I set up a large swap and I've also set up the ccache which may speedup a little after the crash.

I remember that I did try "CTRL+ALT+DEL" in such situations before, and most times it did not work but for one or two times it worked occasionally. I will try it again next time.
