gcc/fortran/ChangeLog:

2015-10-25  Andre Vehreschild  <vehre@gcc.gnu.org>

	PR fortran/66927
	PR fortran/67044
	* trans-array.c (build_array_ref): Modified call to
	gfc_get_class_array_ref to adhere to new interface.
	(gfc_conv_expr_descriptor): For one-based arrays that
	are filled by a loop starting at one the start index of the
	source array has to be mangled into the offset.
	* trans-expr.c (gfc_get_class_array_ref): When the tree to get
	the _data component is present already, add a way to supply it.
	(gfc_copy_class_to_class): Allow to copy to a derived type also.
	* trans-stmt.c (gfc_trans_allocate): Do not conv_expr_descriptor
	for functions returning	a class or derived object. Get the
	reference instead.
	* trans.h: Interface change of gfc_get_class_array_ref.

gcc/testsuite/ChangeLog:

2015-10-25  Andre Vehreschild  <vehre@gmx.de>

	PR fortran/66927
	PR fortran/67044
	* gfortran.dg/allocate_with_source_10.f08: New test.
	* gfortran.dg/allocate_with_source_11.f08: New test.
	* gfortran.dg/class_array_15.f03: Changed count of expected
	_builtin_frees to 11. One step of temporaries is spared, therefore
	the allocatable component of that temporary is not to be freeed.
