Description Agostino Sarubbo gentoo-dev 2023-04-10 12:54:33 UTC

Issue: sys-devel/gcc-11.3.1_p20230303 adds -Werror flag on its own.
Discovered on: amd64 (internal ref: ci)

NOTE:
-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.

build log and emerge --info (compressed because it exceeds attachment limit, use 'xzless' to read it)
Comment 2 Mike Gilbert gentoo-dev 2023-04-10 18:37:58 UTC 
It looks like -Werror only appears when building libgfortran.
