name-lookup.c (check_for_out_of_scope_variable): Avoid ICE by returning when TREE_TYPE is error_mark_node.


	* name-lookup.c (check_for_out_of_scope_variable): Avoid ICE by
	returning when TREE_TYPE is error_mark_node.
	* typeck.c (require_complete_type): Return error_mark_node if
	value's type is an error_mark_node.

	* g++.dg/lookup/forscope2.C: New test case.
