I actually vaguely recall why this should be a warning, and not be checked for
at runtime. This is for legacy codes using real :: a(1) instead of real ::
a(*). Something like

SUBROUTINE S1(a)
  INTEGER :: a(10)
  a(10)=0
END SUBROUTINE

SUBROUTINE S2(a)
  INTEGER :: a(1)
  CALL S1(a)
END SUBROUTINE

INTEGER :: a(10)
CALL S2(a)
END

'works just fine'...
