re PR fortran/83118 (Bad intrinsic assignment of class(*) array component of derived type)
2018-06-21 Paul Thomas <pault@gcc.gnu.org>
PR fortran/83118
* resolve.c (resolve_ordinary_assign): Force the creation of a
vtable for assignment of non-polymorphic expressions to an
unlimited polymorphic object.
* trans-array.c (gfc_alloc_allocatable_for_assignment): Use the
size of the rhs type for such assignments. Set the dtype, _len
and vptrs appropriately.
* trans-expr.c (gfc_trans_assignment): Force the use of the
_copy function for these assignments.

* gfortran.dg/unlimited_polymorphic_30.f03: New test.
