--- 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.
