Description Gavin Barraclough 2008-12-16 15:00:14 PST 
This implies that a different bug exists somewhere – that the value in the upper word is being relied on, which should not be the case.  Should investigate.
Comment 1 Gavin Barraclough 2010-03-02 18:01:31 PST 
This bug is old, and was quite possibly inaccurate in the first place.
Now, we certainly do always ensure the top word is a sign extend of the low word, if using 32-bit representation on 64-bit.

That said, we don't use 32-bit representation on 64-bit, so this is utterly uninteresting.
