             Bug #: 13808
           Summary: -Wdangling-field warning should check in-class
                    initializers
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++11
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: richard-llvm at metafoo.co.uk
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


struct S { const int &a; S() : a(0) {} } s;                                     
struct T { const int &a = 0; } t;

produces:

<stdin>:1:34: warning: binding reference member 'a' to a temporary value
[-Wdangling-field]
struct S { const int &a; S() : a(0) {} } s;
                                 ^
<stdin>:1:23: note: reference member declared here
struct S { const int &a; S() : a(0) {} } s;
                      ^

We should also issue a diagnostic for the in-class initializer case.
