--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
If I replace the lines

  integer,parameter:: qp = selected_real_kind(30), dp = kind(1d0)
  real(qp),parameter:: q1 = 1, q23(1) = 2*q1/3

with

  real(qp),parameter:: q1(1) = 1, q23(1) = 2*q1/3
  real(dp),parameter:: d1 = 1, d23(1) = real(2*q1(1)/3,dp)

I get

   real(dp),parameter:: d1 = 1, d23(1) = real(2*q1(1)/3,dp)
                                             1

I don't get any warning with gfortran 5.4.0.
