--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Up to r200946 (2013-07-14, 4.9) gfortran gives an error

Error: Ambiguous interfaces 'disp2' and 'disp1' in generic interface 'disp' at
(1)

>>From at least r201266 (2013-07-26) gfortran accepts the code. I did not find
any obvious culprit in this range for the change in behavior. I also don't know
what is the correct behavior.
