Created attachment 923476 [details] build and terminal buffer logs plus emerge --info and the ebuild itself While emerge was compiling hyprland (ebuild in attachment) at the very beginning I terminated it and then I noticed the fans spun up. I issued a ps command and saw gcc and ninja running, then I had to kill ninja to stop the ebuild. Details in the attachment, I've also preserved the temp directory, but it's 61MB bzip2 archive so I'll upload it or parts of it on request.
I think I've seen this too.
I think another one of my bugs may also be related
