--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-03-23 08:43:48 UTC --- Can you try either current mainline or 4_6-branch (would be 4.6.0), because quite a few fixes went into those and if the issue isn't a regression and affects only older branches is very unlikely to be fixed.
