	PR fortran/85954
	* resolve.c (resolve_assoc_var): If the target expression is a
	deferred charlen dummy and the associate name shares the
	charlen, generate a new one. Make sure that new charlens are in
	the namespace list so that they get cleaned up.
	* trans-array.c (gfc_is_reallocatable_lhs): Associate names are
	not reallocatable.
	* trans-decl.c (gfc_get_symbol_decl): Put deferred character
	length dummy and result arrays on the deferred initialization
	list so that the variable length arrays can be correctly dealt
	with.
	* trans-expr.c (gfc_conv_string_length): Return if 'expr' is
	NULL rather than ICEing..
