Yes, "guix build zile" fails again at GCCs build. I attached the build 
log just to be sure.

It got 4GB of RAM but none of swap. dmesg really shows something, please 
see attachment. I'll try hooking up some swap and see how it goes.

I'm curious: How did you compile gcc in the past, where resources were 
even more scarce? Did you always have a good load of swap for it to 
succeed? I remember the rule "swap is 2 times ram", though in recent 
years some are convinced that it worn off given the ever bigger RAM.
