Hard to say.

If it is fixable, it would be great to fix it.  Changing to 13 for
(some?) macos seems lower risk to everytbody else.

In general we like the branch to work :-) Who is motivated to fix what
is of course another question!  So if you  are up for figuring it out,
great, but we have to be careful not to cause regressions on platforms
that people won't be able to test on, so I am reluctant to land patches
into gcc unless everybody thinks they are clearly right with low risk.
