--- Comment #8 from Jason Merrill <jason at gcc dot gnu.org> --- The problem seems to be that we inlined the function, but DECL_POSSIBLY_INLINED remains unset, so dwarf2out doesn't think it needs to call dwarf2out_abstract_function. There also doesn't seem to be a cgraph edge for the inlined function call; I'm guessing that the function was inlined in the initial compilation, and this relationship is forgotten by the time we get to LTO. So, doesn't look like a dwarf2out bug.
