The hardware has a memory bus arbiter ASIC that does not handle mis- aligned references for 2-byte accesses ending on 1 or 5. So this construct will fail indeterminately. I passed on the information given us about the -mstrict-align and it appears to have cleared up the issue with odd alignment offsets.
