--- Comment #5 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
Unfortunately I can still reproduce this with 483.xalancbmk on spec2006.

It seems to indeed happen only with -flto so I have no idea how to reduce it..

As of g:8833eab4461b4b7050f06a231c3311cc1fa87523 I still get

during RTL pass: expand
