--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Started to ICE with r229954, before that an error is reported:

pr78619.f90:3:17:

    z = sign(1.0, f)
                 1

Warning: Non-RECURSIVE procedure ‘f’ at (1) is possibly calling itself
recursively.  Declare it RECURSIVE or use ‘-frecursive’
pr78619.f90:3:17:

    z = sign(1.0, f)
                 1

Error: ‘b’ argument of ‘sign’ intrinsic at (1) must be the same type and kind
as ‘a’
