I can reproduce problems on x86_64, although with different bad results 
from x86.  But, you should still file a *new* bug for these problems, 
since it seems quite clear that the range-reduction-accuracy problems can 
sensibly be fixed separately from the not-correctly-rounded issues this 
bug is about.  In general, unless it is clear that two issues can only 
sensibly be fixed together, they should have *separate* bugs filed; always 
err on the side of filing duplicate bugs rather than confusing an existing 
bug with something that might not be fixed together with the originally 
reported issue.
