Description Daniel Santos 2020-02-10 15:24:27 UTC

Linus has added a nice optimization for those of us with lots of CPU cores/threads/ALUs, but testing reveals that it tends to express the (known) race condition in GNU make 4.2.1.  As such, an ebuild warning, uname -r check, or DEPEND restriction should probably be added to sys-devel/make.  Or maybe ">=sys-devel/make-4.3" added to gentoo-sources-5.6?  It's currently at RC1.

I'm pretty sure we already have the necessary patch backported to make-4.2.1. See bug 664632.
