I fixed this bug today, so it might help. But it is related to COMDAT
functions and I don't think fortran actually produce them.
We do reachability after clonning, there must be actually reason to keep
the clone, so we need to debug it.
I will try to look into it tomorrow if other new issues won't stop me
(I just got profile feedback working with LTO, it might be also
interesting if it helps your app).
