This starts passing for me between 2007-03-10 and 2007-03-20.  Andrew, if it
fails for you with a later mainline than that, perhaps it's an intermittent
failure rather than a regression.

I was testing at the time "4.3.0 20070306" and I tested with yesterday's trunk
and it passes.  It also works on the 4.2 branch as of "4.2.0 20070415".

------- Comment #3 from janis at gcc dot gnu dot org  2007-04-23 23:28 -------
A regression hunt on powerpc-linux for mainline shows that it was fixed by this
patch:

    http://gcc.gnu.org/viewcvs?view=rev&rev=122829

    r122829 | mmitchel | 2007-03-12 00:26:39 +0000 (Mon, 12 Mar 2007)

That patch was added to the 4.2 branch at the same time, and the test now
passes on that branch.

The failure still occurs on the 4.1 branch as of 2007-04-19.

Yeah, this is fixed by the PR31038 patch and that patch fixes this even
on gcc-4_1-branch.  But the original PR31038 testcase still ICEs on 4.1 even
with PR31038 patch.
