Wrong C++ generated with first class function in collection and a struct parameter

	#Import "<std>"
	
	Using std.collections
	
	Struct Event
	
		Field data : Int
	
	End Struct
	
	Alias EventCb : Void( event : Event )
	
	Function Main()
	
		Local dict : StringMap< EventCb > = New StringMap< EventCb >()
	
	End Function

Using the above code, the wrong C++ code is generated. Works fine when Event is a class.
