--- Comment #18 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
since this PR, and the related PR77278 can presumably only be fixed by changing
libgfortran abi (at least if I understand Richard's suggestion for fixing
this). The announced major version bump of libgfortran
(https://gcc.gnu.org/ml/gcc-patches/2016-10/msg01376.html) could be a good
opportunity for this change. It is the major thing holding back the use of LTO
with Fortran projects, I think.
