This patch adds: (i) Default initializers for parameterized arrays; (ii) Fixes ordinary assignment of PDTs by implementing the same deep copy mechanism as for derived types with allocatable components; and (iii) Fixes the len parameter checking, which failed where the dummy type had an assumed parameter.
I have in fact committed this patch as revision 256335 since it is safe for anything other than PDTs. 2018-01-08 Paul Thomas <pa...@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. 2018-01-08 Paul Thomas <pa...@gcc.gnu.org> PR fortran/83611 * gfortran.dg/pdt_15.f03 : Bump count of 'n.data = 0B' to 8. * gfortran.dg/pdt_26.f03 : Bump count of '_malloc' to 9. * gfortran.dg/pdt_27.f03 : New test.
