Right, more tunnels in the rabbit hole. :) Can you please upload these new .c
and .sh files dropped after the assertion?

--- Comment #6 from Mark Millard ---
(In reply to commit-hook from comment #5)
I finally got around to testing the patch with a
rebuild attempt for graphics/mesa-dri . It just
failed a different assert:
Core was generated by `/usr/bin/cc -cc1 -triple powerpc64-unknown-freebsd13.0
-emit-obj -disable-free -'.
