+ * gfortran.h: Add 'must finalize' field to gfc_expr and

+ gfc_is_alloc_class_array_function.
+ * expr.c (gfc_is_alloc_class_scalar_function,

+ * 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.
