re PR fortran/83611 ([PDT] Assignment of parameterized types causes double free error in runtime)

2018-01-08  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/83611
	* decl.c (gfc_get_pdt_instance): If parameterized arrays have
	an initializer, convert the kind parameters and add to the
	component if the instance.
	* trans-array.c (structure_alloc_comps): Add 'is_pdt_type' and
	use it with case COPY_ALLOC_COMP. Call 'duplicate_allocatable'
	for parameterized arrays. Clean up typos in comments. Convert
	parameterized array initializers and copy into the array.
	* trans-expr.c (gfc_trans_scalar_assign): Do a deep copy for
	parameterized types.
	*trans-stmt.c (trans_associate_var): Deallocate associate vars
	as necessary, when they are PDT function results for example.

	PR fortran/83731
	* trans-array.c (structure_alloc_comps): Only compare len parms
	when they are declared explicitly.
