--- Comment #13 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The change of behavior occurred between r203500 (2013-10-13) and r203859
(2013-10-19). Since libgfortran/io/write_float.def has not change between
r199598 and r206296 (Update copyright years in libgfortran), the change of
behavior is not directly related to libgfortran/io/write_float.def, but
probably to change in optimization.
