           Summary: basicaa returns noalias for aliasing pointers,
                    miscompiles MiBench/consumer-typeset
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Global Analyses
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sabre at nondot.org


In the attached heavily reduced testcase, basicaa returns noaa for two pointers that overlap.  This causes 
miscompilation of consumer-typeset.
