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.
