* interface.c (compare_rank): Don't try to retrieve CLASS_DATA
from symbol marked unlimited polymorphic.
* resolve.c (resolve_structure_cons): Likewise.
* misc.c (gfc_typename): Don't dereference derived->components
if it's NULL.

PR fortran/82257
* gfortran.dg/unlimited_polymorphic_28.f90: New test.
