 I haven't looked at this particular problem in over a year, but from
 memory I think there may have been some follow-on posts that stated
 the underlying problem was inconsistent treatment of paradoxical
 subregs on WORD_REGISTER_OPERATIONS machines.
 
 My patch should be regarded as a band-aid rather than a proper
 solution.

    What is the status of this report? Alan, you had a patch
    but it is not applied, because Jeff warned against it. But
    you seemed to have at least understood what is going wrong.
    Is there any progress on this question?
    
    Thanks
      Wolfgang
