--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
This likely due to r185433. This fixed by the following patch

Regtesting in progress. Note that the block
- if (dtp->u.p.current_unit->round_status != ROUND_UNSPECIFIED
- && dtp->u.p.current_unit->round_status != ROUND_PROCDEFINED)
appears in several places in libgfortran/io/write_float.def and I fail to see
the logic.
