--- Comment #7 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > I don't understand how that applies in the context of Joseph's > build-many-glibcs.py script. This PR is about a compiler issue so I presume that build-many-glibcs.py tests the compiler at some point? If so, then you either need to make sure that it tests the trunk compiler and not the compiler from the 9 branch, or else you need to configure the compiler from the 9 branch with --enable-checking=release,misc.
