--- Comment #4 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
OK. I can reproduce the ICE in free form (*.f90) by replacing '80 000 000' with
'80000000'. The change occurred between r226476 (2015-08-02, error) and r227016
(2015-08-19, ICE), likely r226732 (pr59746).

Agreed, although the original error

Error: PROCEDURE attribute conflicts with COMMON attribute in 'xx' at (1)

may not be obvious to understand.
