--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. Seems to be a quite recent regression.
1001 location_t r =
1002 linemap_position_for_line_and_column (set, map, line, column);
1003 if (linemap_assert_fails (r <= set->highest_location)
1004 || linemap_assert_fails (map == linemap_lookup (set, r)))
1005 return loc;
the map == linemap_lookup (set, r) part fails.

fixes it (pasto in original fix?) and seems to preserve fixing the original PR
(but that had no testcase added).
