--- Comment #5 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Should be fixed by r234087+r234088:
r234087: "[PATCH 1/2] PR c++/70105: Defer location expansion until
diagnostic_show_locus"
https://gcc.gnu.org/ml/gcc-patches/2016-03/msg00583.html
r234088: "[PATCH 2/2] PR c++/70105: prevent nonsensical underline spew for
macro expansions"
https://gcc.gnu.org/ml/gcc-patches/2016-03/msg00585.html
Additionally verified by rebuildling tree-complex.c, which now emits just:
