The test case was fixed for 4.6 by r159644. However, that patch
<http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01528.html> was described as a
minor improvement to double-word register allocation and not a correctness fix,
so the underlying bug may be latent on trunk.
I'll investigate some more tomorrow.
