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.
