Comment (by dfeuer):

 I don't know if this is related. I asked Johan Tibell the other day why
 `unordered-containers` marks almost everything `INLINE` instead of
 `INLINABLE`. He replied that when an `INLINE` function calls an
 `INLINABLE` one, we end up calling to specialize. He also indicated that
 he'd opened a ticket about this long ago; I don't know which one.
