--- Comment #4 from H.J. Lu <hjl.tools at gmail dot com> ---
line-map.c has

 linemap_assert (reason != LC_ENTER_MACRO);
  line_map_ordinary *map
    = linemap_check_ordinary (new_linemap (set, start_location));
  map->reason = reason;

We get here with reason != LC_ENTER_MACRO and create linemap with
start_location >= LINE_MAP_MAX_LOCATION.
