------- Comment #3 from vmakarov at redhat dot com 2008-07-07 18:30 -------
Liveness info was missed in data-flow equation calculation for set free when
the save/restore placement optimization was written.
Fortunately, the case was catched by an assertion.
The patch solving the problem has been submitted (please see above).
