	* src/parser.y (release_const_tree): New routine used to release
	exprtrees that we discard during parsing.

	array_expressions: The various NUMBERS used in this rule are
	never actually linked into the ExprTree, we are only interested in
	them to pull a couple of integers from it.  We now release them
	after we construct the formula.  This fixes the leaks reported by
	Morten.
