This is confusing.

Grepping through the gimple dump for the length .y , I see

  sizetype .y.16;
        integer(kind=8) .y;
            .y = _24;
            .y.15_29 = .y;
            .y.16 = (sizetype) .y.15_29;
            y.dtype.elem_len = .y.16;
              character(kind=1)[0:][1:.y] * D.3961;
                .y.19_40 = .y;
                _41 = _39 * .y.19_40;
                .y.20_44 = .y;
                _45 = _gfortran_compare_string (.y.20_44, _43, 3, &"abc"[1]{lb:
1 sz: 1});
            .y = {CLOBBER};


so cheking the indentation, .y is correctly declared.

_29 seems to be a variable that is introduced by gimple, possibly
incorrectly. I am not sure how to debug this, or if this is even
a front-end error, or just exposes something in the middle end.
