--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> --- Shouldn't the GIMPLE front-end give a better error message for invalid input? I realize -fgimple is an experimental feature but it seems that we should at least aim for the same robust error handling in the front-end as everywhere else.
