https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: media-gfx/darktable-4.0.1-r1 overwrites user's optimization (-O*). Discovered on: amd64 (internal ref: ci) NOTE: unless there are known issues with -O* configured by the user, the build system should not overwrite -O*.
Created attachment 842967 [details] build.log.xz build log and emerge --info (compressed because it exceeds attachment limit, use 'xzless' to read it)
Seeing as this has not been updated for 4.2.0 and newer, assuming optimistically that this has been taken care of upstream.
