------- Comment #17 from jamborm at gcc dot gnu dot org 2009-08-06 12:09 -------
New SRA scalarizes the unions in this testcase and so this is no
longer a 4.5 regression. I have committed a testcase for reference
and am updating relevant bugzilla tags/summary now.
As I won't be backporting new SRA to any of the regressing versions, I
am no longer really interested in this bug and will remove myself from
the CC list too. Feel free to re-add me if anything I should know
about arises.
