--- Comment #5 from anlauf at gcc dot gnu.org ---
I doubt that the code is valid.  NAG rejects it:

NAG Fortran Compiler Release 7.2(Shin-Urayasu) Build 7200
Warning: pr104130.f90, line 7: Unused dummy variable X
Error: pr104130.f90, line 3: Incorrect data type CLASS(*) (expected INTEGER)
for argument X (no. 1) of S


Starting with r14-870, the testcase is also rejected by gfortran:

pr104130.f90:3:9:

    3 |   call s(transpose(z))
      |         1
Error: Unlimited polymorphic actual argument at (1) is not matched with either
an unlimited polymorphic or assumed type dummy argument


Updating known-to-work.
