--- Comment #20 from David Malcolm <dmalcolm at gcc dot gnu.org> --- In r230331 I added a range-packing optimization; looks like I forgot to update linemap_position_for_loc_and_offset accordingly. Sorry. The input "offset" is a column offset, and that is no longer applicable as a offset to loc. I'm investigating a fix.
