--- Comment #6 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to Jan Hubicka from comment #0) > One obvious thing is that linemap_line_start takes argument 3 to be max > column hint, but we pass current_col that is not cool. If I remember correctly, the column hint is only used to try to optimize memory. That is, if you provide a bad hint, then memory will be wasted (a too short hint may require additional maps for larger columns; a too large hint requires additional maps to encode the same number of lines). However, unless you pass a value of 100000 or more, it should not affect the actual behavior.
