Re: Architectures where unaligned access is (not) OK?

Sparc is definitely not ok. For evidence, see #721617, liblo was trying to fetch a double from a 4-byte aligned address. Experience with liblo shows that other architectures are just fine (or at least are just slower) with this type of unalignment.

IME, sprac buildds are the only ones where where unaligned access in a build-time test suite triggers SIGBUS/SIGSEGV.

Now that sparc is no long a release architecture, these kind of problems are likely to go unnoticed. :-(
