https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: games-engines/love-11.4 fails to compile (lto). Discovered on: amd64 (internal ref: lto_tinderbox) NOTE: This machine uses lto with CFLAGS=-flto -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing
Created attachment 792077 [details] build.log build log and emerge --info
This is triggered by the presence of -Werror=strict-aliasing in CFLAGS, regardless of whether LTO has been enabled or not. Oh, and just to keep track of things - as of a few minutes ago, the live ebuild still suffers from this as well.
Oh, and interestingly enough I am unable to reproduce this error on one of my machines in spite of all of them being up to date on the stable profiles. In light of which I don't think I'll even bother reporting this upstream.
