--- Comment #9 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
Its not really a glitch. In this case reversion has occurred so i can only
approximate where in the string the error occured. I can improve on it with:
offset = fmt->reversion_ok ? fmt->format_string_len + 2:
dtp->format_len - fmt->format_string_len;
I don't think I can do better for now. Of course we want diagnostics to be
helpful, but they can not be perfect. I would suggest we commit the patch for
now.
