No worries, I have found the culprit in the Fortran front-end, where we
build the P_P_E with no regards to type:

  tmp4 = fold_build2 (POINTER_PLUS_EXPR, pchar_type_node, dest,
                      fold_convert (sizetype, slen));

(This problem is present in mainline as well).

I'm working on a patch.
