             Bug #: 13217
           Summary: Crash on in-class initialization of member of struct
                    in union
           Product: clang
           Version: 3.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
        AssignedTo: unassignedclangbugs at nondot.org

a.cpp:
struct A {
  union {
    struct {
      int a = 0;
    };
  };
};


clang++ -std=c++11 -c a.cpp causes clang to crash with a segmentation fault.


clang++ -c a.cpp yields:

a.cpp:4:13: warning: in-class initialization of non-static data member is a
C++11 extension [-Wc++11-extensions]
      int a = 0;
            ^
a.cpp:3:5: error: union member '' has a non-trivial constructor
    struct {
    ^

followed by crash with a segmentation fault.
