re PR c++/3761 (ICE in check_template_shadow, at cp/pt.c:2013, with friend and strange class hierarchy)

Browse Source 
PR c++/3761
	* name-lookup.c (push_class_level_binding): Don't pass a
	TREE_LIST of ambiguous names to check_template_shadow as it
	only handles declarations. Instead, pull the declaration
	out and pass that.

	PR c++/3761
	* g++.dg/lookup/crash4.C: New test.
