re PR c/64778 (ICE on invalid code on x86_64-linux-gnu: tree check: expected class ‘type’, have ‘exceptional’ (error_mark) in create_tmp_from_val, at gimplify.c:491)

	PR c/64778
	* c-typeck.c (convert_arguments): Return -1 if there are
	error_args, even if we've diagnosed too many arguments.

	* gcc.dg/pr64778.c: New test.
