--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think LTO complains that the fortran frontend uses ssize_t but the C code
size_t for the hidden length argument.

I think the TBAA warning is bogus here since signed and unsigned long
inter-operate.  If the fortran frontend is suggesting size_t then it should
better
also use size_type_node for argument passing.

Honza, shouldn't we suppress the TBAA warning here?
