This might have been fixed by Janus patch:

2016-12-04  Janus Weil  <janus@gcc.gnu.org>

        PR fortran/78618
        * intrinsic.c (gfc_convert_type_warn): Do not set the full typespec for
        the conversion symbol, but only type and kind. Set the full typespec
        for the expression.
        (gfc_convert_chartype): Ditto.

Gerhard can re-do your testing.  I seem to have good luck with FreeBSD
in testing this.
