This is just a guess, but I think you need to use $1 instead of 1 in your add. The $ tells gcc the value is an immediate, and I think otherwise 1 is treated as a memory address. There probably isn't a version of add that operates on memory (especially unaligned memory) so that might not really be the problem.
