This part of the heterogeneous support being broken was my fault. I fixed it in r31535. I will try to spend some time over the next month or so fixing heterogeneous support in the one-sided code. Right now the packed datatype representation will not work if sizeof (int) is not consistent. Not sure if we ever claimed to support this case though.
