It's been a few years now since I worked on that architecture, but
Sparc is somewhat-modern and resolutely unaligned-unfriendly. It's
just that you can optionally install a trap handler that will do super
slow non-atomic misaligned access in software instead of blowing up
with SIGBUS. With the Sun toolchain you did that explicitly by
building with -misalign (though it's possible that more recent
compilers might be doing that without being asked?).
