           Summary: Invalid warning on references in structs
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: chris at bubblescope.net

The following code produces an invalid warning, as the reference being returned
is itself a reference, not stack memory. Code like this exists in
boost::parameter.


struct X
{ int& i; };

int& getX(X x)
{ return x.i; }

-------

temp.cc:5:10: warning: reference to stack memory associated with local variable
      'x' returned
{ return x.i; }
