--- Comment #3 from David Malcolm <dmalcolm at gcc dot gnu.org> --- I'm still working on reproducing this. Looking at the stderr from attachment 47857, this seems reminiscent of g:b4f3232d6979022a36b4055d7d3aaba693a39938 (PR c++/70105 and PR c/68473) and also g:876217ae71cf0b34490f8f53bb2a12d99d8baa7a (PR other/69554)
