Therefore we can compile C file with '-fcheck-pointer-bounds -mmpx -flto -c', then compile fortran (or any other) file with '-c -flto' and finally pass generated objects to LTO. It may be inconvenient to avoid '-fcheck-pointer-bounds' for nonc-C files when you work with mixed codes. To handle it I may use langhooks and ignore '-fcheck-pointer-bounds' when it's not supported for used language.
