I think you still need something to avoid the misalignment trap in the 'false' case. If they only need to be aligned 'for efficiency' then I'd assume the cpu (or whatever normally processes them) is ok with 4-byte alignment even though 'ldd' (8 byte load?) faults. Which would mean you need to read them with two 4-byte loads. Especially if 'fn' isn't just one of a couple of specific values that can be forced to be aligned. But the code might just be completely broken. (as suggested elsewhere). David - Registered Address Lakeside, Bramley Road, Mount Farm, Milton Keynes, MK1 1PT, UK Registration No: 1397386 (Wales)
