Comment (by kencu):

 Your most effective method of resolving issues with gcc-10 (or, to be
 honest, most any gcc) on darwin at this moment in time is probably to go
 here:

 https://github.com/iains/gcc-10-branch

 and open an issue in this github branch directly with the gcc darwin
 maintainer. Most likely, he has already fixed it and can point you to the
 exact commit you need.

 If not, if he has time, he will generally be very happy to try to work
 through a proper fix for you, and then it will be upstreamed in due course
 if it works out.

 There is a separate gcc bug tracking system of course. It is possible that
 Iain might send you there to open a ticket instead, but lately he has been
 most responsive there on github in the gcc repos he is working with.
