https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: dev-erlang/jiffy-1.1.1 adds -Werror flag on its own. Discovered on: amd64 (internal ref: usr-merge_tinderbox) NOTE: (USR-MERGE-SYSTEM) in the summary means that the bug was found on a machine that runs default/linux/amd64/17.1/systemd/merged-usr profile but this bug MAY or MAY NOT BE related to the new profile. -Werror is not recommended for releases and should always be disabled when encountered in build-logs, because there are numerous cases where this breaks without purpose.
