Created attachment 578972 [details] build.log.xz After updating my system to a 17.1 profile, gcc 9.1 w/PGO+LTO failed to compile. The same package with the same settings compiled fine after the last revbump recently. emerge --info: Portage 2.3.67 (python 3.6.8-final-0, default/linux/amd64/17.1/desktop/gnome/systemd, gcc-9.1.0,
