For 4.22(?). This fixes a segfault in the Ocaml runtime on ARM.

It's not a regression vs 4.21, but it is deterministic and easy to fix.
Technically patch 1 is sufficient to fix the segfault, but producing an
unconditional exception is almost as useless.

Thanks.  I've managed to get some testing in GitlabCI showing the segfault:

and things working properly with this series in place:
