--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This regressed everywhere with -O -Wunused -fno-use-cxa-atexit starting with
r204265, on Solaris that is just the default, while on various other targets it
is not.  mark_used is no longer called on the TREE_STATIC global VAR_DECL,
eventhough it has a non-trivial destructor.  Jason, can you please have a look?
