I expect it to cause quite some problems this year as well.

The decision on whether or not to run the included tests is eventually
yours, but I found it extremely helpful to run the testsuite this time
(and I wouldn't have done it if I didn't have the MacPorts package at
hand and if Martin didn't add the additional support to make it work
out of the box).

Martin fixed a number of bugs that would have resulted in crashes of
the program for anyone compiling against libc++ (that includes macOS,
FreeBSD etc.) and we would be shipping a broken binary. I remember
John Bowman spending considerable amount of time diagnosing crashes of
Asymptote on someone else's Mac (probably running OS X 10.9) a few
years ago thanks to exactly the same dispute of how the developers
interpret the C++ standard.
