--- Comment #5 from Sam James <sjames at gcc dot gnu.org> --- I sort of wonder if we should have some smoketest in the testsuite where we just try include every header with Clang optionally. I don't test Clang much and only hit this because our compiler-rt-sanitizers package defaults to building with it for some reason I forget.
