           Summary: Wrong error message
           Product: gcc
           Version: 3.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: bonzini at gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org

This error has been wrong for a long time.  It gives an erroneous "wrong 
arguments to binary !=" even though there is no != in the source code.

The distilled test case is extremely simple:

struct a {
};

int
bug(struct a *m)
{
  return (*m || 1);
}

Thank you very much,

Paolo
