2015-02-06  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/63205
	* gfortran.h: Add 'must finalize' field to gfc_expr and
	prototypes for gfc_is_alloc_class_scalar_function and for
	gfc_is_alloc_class_array_function.
	* expr.c (gfc_is_alloc_class_scalar_function,
	gfc_is_alloc_class_array_function): New functions.
	* trans-array.c (gfc_add_loop_ss_code): Do not move the
	expression for allocatable class scalar functions outside the
	loop.
	(conv_array_index_offset): Cope with deltas being NULL_TREE.
	(build_class_array_ref): Do not return with allocatable class
	array functions. Add code to pick out the returned class array.
	Dereference if necessary and return if not a class object.
	(gfc_conv_scalarized_array_ref): Cope with offsets being NULL.
	(gfc_walk_function_expr): Return an array ss for the result of
	an allocatable class array function.
	* trans-expr.c (gfc_conv_subref_array_arg): Remove the assert
	that the argument should be a variable. If an allocatable class
	array function, set the offset to zero and skip the write-out
	loop in this case.
	(gfc_conv_procedure_call): Add allocatable class array function
	to the assert. Call gfc_conv_subref_array_arg for allocatable
	class array function arguments with derived type formal arg..
	Add the code for handling allocatable class functions, including
	finalization calls to prevent memory leaks.
	(arrayfunc_assign_needs_temporary): Return if an allocatable
	class array function.
	(gfc_trans_assignment_1): Set must_finalize to rhs expression
	for allocatable class functions. Set scalar_to_array as needed
	for scalar class allocatable functions assigned to an array.
	Nullify the allocatable components corresponding the the lhs
	derived type so that the finalization does not free them.
