Comment (by ryankanno):

 Replying to [comment:11 jmroot]:
 > The first thing you could rule out is the other variants. See if
 building with `-lto`, `-optimizations`, or both has any effect on this
 (still with `+universal` of course; we already know `-universal` is OK).
 If not, and if there's an older version that was known not to have this
 issue, bisecting would certainly be helpful. If there's no known good
 version, going back to older versions may be futile, but I guess it's
 still data.

 Great idea. Following your advice, here's a matrix of what I came up with
 - it looks like the arm64 archs are failing.

 Will continue to add more data points from older portfiles as I try them
 out.
