--- Comment #42 from Jonathan Wakely <redi at gcc dot gnu.org> --- The bootstrap regression in the library is fixed, but there's still a problem with the compiler that makes -fvtable-verify=std incompatible with init_priority(99). Either we should fix that so it works, or reject init_priority(99) with a descriptive diagnostic when -fvtable-verify=std is used. The latter would save time trying to figure out why it's failing.
