Description Andreas K. Hüttel archtester gentoo-dev 2018-06-09 19:38:50 UTC
Bug filed mostly for tracking purposes...

gcc-7 has a so-far unfixed bug when dealing with 128bit floats (but only for specific processor settings on amd64).

This manifests itself as glibc (sic) test failures.

I can't reproduce this myself anymore.
