--- Comment #13 from Richard Biener <rguenth at gcc dot gnu.org> ---
This is caused by the fixup I added in r16-7550-gf34a8411afefac.  The
fixup_noreturn_call causes a debug stmt to be elided during inlining
but then copy_debug_stmts comes along and calls update_stmt on it again,
putting SSA operands back.
