--- Comment #9 from Ryan Schmidt <gcc at ryandesign dot com> --- Is it safe to use the patch? Will a gcc built with the patch produce correct code? If so, I would like to include it in MacPorts so that I can update our gcc8 port to a newer version. Because of this problem, we have not been able to do so since June 2017.
