You may wish to do your own build without as much optimization, of
perhaps just openssl. This can be done cross on a fast machine, via build.sh.

So the issue was *wnumtop not being zero, in frame 2, and then one has to figure out why.

Unfortunately you are in a fairly sparse space, in terms of how many
people are using sparc. But I would expect some others, and there are
test runs in qemu:
http://releng.netbsd.org/b5reports/sparc/
but only on head, not the netbsd-9 branch.
If you have a fast machine and can run anita/qemu, you could test the
build you are installing. I can try to test a build of netbsd-9.
