--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Seems this doesn't ICE starting with r248863, so it likely just went latent.
Maybe we should just error out on selective scheduling and explicit
-fvar-tracking-assignments or -gstatement-frontiers, this scheduler really
can't handle any debug insns well.
