I think there is a smaller probability that this bug occurs in gcc4.3 because
it is based on the old RA. IRA uses hard registers more effectively and
frequently than the old RA and therefore it stresses the reload pass more and
as the result reload bugs occur more frequently with IRA.
But if it is present in gcc4.3, the patch should be applied too. Even more I
guess that the patch is pretty safe and could be applied to gcc4.3 in any case.
If you want you could apply it to gcc4.3-branch.
