This seems to have disappeared between r161659 and r163636.
I can't reproduce it anymore with r166868/x86_64-linux.

Mine.
On trunk I am able to reproduce the ICE.
This is fixed in the Graphite branch, probably by the cleanup of the IV
canonicalization.
I will investigate a little bit more what happens in trunk, and if this is
really fixed by my changes in the Graphite branch I will close this PR when
these changes will be committed to trunk.
Sebastian
