Hi Maxim,


Which hardware do you test this on?  I'm using one of the ColdFire boards
and it works fine.  I'm guessing that your CPU does not have a misalignment
module.  Is it the case?


I am using a MC68302 (68K) and it is not supporting unaligned
read/write as the ColdFire.

Does the following /untested/ patch fix the problem for you?
