------- Comment #9 from rguenth at gcc dot gnu dot org 2008-06-04 08:59 -------
The only code-generation changing part of the patch is
(insert_fake_stores): Handle all component-ref style stores
in addition to INDIRECT_REF. Also handle complex types.
but that only fixes a missed-optimization, so it probably makes the problem
latent on the trunk.
