--- Comment #9 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
The last token is a CPP_PRAGMA_EOL, and has a line number 2,
while the include file has only one line, so it is similar to an EOL position.
I guess therefore this fails to add a column?
1002 location_t r =
1003 linemap_position_for_line_and_column (set, map, line, column);
1004 if (linemap_assert_fails (r <= set->highest_location)
1005 || linemap_assert_fails (map == linemap_lookup (set, r)))
1006 return loc;
(gdb) p tok[0]
$30 = {type = CPP_EOF, keyword = RID_MAX, flags = 64 '@', implicit_extern_c =
false, error_reported = false,
purged_p = false, tree_check_p = false, main_source_p = true, location =
255712, u = {tree_check_value = 0x0,
value = 0x0}}
(gdb) p tok[-1]
$31 = {type = CPP_PRAGMA_EOL, keyword = RID_MAX, flags = 0 '\000',
implicit_extern_c = false, error_reported = false,
purged_p = false, tree_check_p = false, main_source_p = false, location =
251552, u = {tree_check_value = 0x0,
value = 0x0}}
location_t r =
1003 linemap_position_for_line_and_column (set, map, line, column);
(gdb) p r
$68 = 252480
(gdb) p *map
$70 = {<line_map> = {start_location = 251584}, reason = LC_LEAVE, sysp = 0
'\000', m_column_and_range_bits = 12,
m_range_bits = 5, to_file = 0x2ac9800 "pr99446-1.h", to_line = 2,
included_from = 238400}
(gdb) p *result
$74 = {<line_map> = {start_location = 251616}, reason = LC_LEAVE, sysp = 0
'\000', m_column_and_range_bits = 12,
m_range_bits = 5, to_file = 0x2b0a2d0 "pr99446.c", to_line = 2, included_from
= 0}
but line 2 does not exist in both files.
