--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Apparently we only disable -fvar-tracking-assignments by default if sel-sched,
not disable it unconditionally.
So, while we could and should change:
  if (debug_nonbind_markers_p == AUTODETECT_VALUE)
    debug_nonbind_markers_p = optimize && debug_info_level >=
DINFO_LEVEL_NORMAL
      && (write_symbols == DWARF2_DEBUG || write_symbols ==
VMS_AND_DWARF2_DEBUG);
to
  if (debug_nonbind_markers_p == AUTODETECT_VALUE)
    debug_nonbind_markers_p
      = (optimize
         && debug_info_level >= DINFO_LEVEL_NORMAL
         && (write_symbols == DWARF2_DEBUG
             || write_symbols == VMS_AND_DWARF2_DEBUG)
         && !(flag_selective_scheduling || flag_selective_scheduling2));
the testcase would still ICE with -gstatement-frontiers.
