Looks like the new test might be failing on macOS/arm64: http://45.33.8.238/macm1/75171/step_11.txt

Maybe it just needs something like 806761a7629df268c8aed49657aeccffa6bca449, but maybe the assert isn't benign.

Do you want to switch the test to use `-mtriple`, or do you want to revert and investigate what's up with the assert?
