            Bug ID: 22924
           Summary: Rejects-valid: braced init list on new[]
           Product: clang
           Version: trunk

Providing 3 initializers for a 3-element array seems like it should work...

$ cat bad_init.cpp
class A {
public:
    A(int a): value(a) { }
    int value;
};
A *bp;
void foo() {
  bp = new A[3] { A(3), A(5), A(7) };
}

$ clang++ bad_init.cpp -std=c++11
bad_init.cpp:8:36: error: no matching constructor for initialization of 'A'
  bp = new A[3] { A(3), A(5), A(7) };
                                   ^
bad_init.cpp:3:2: note: candidate constructor not viable: requires single
      argument 'a', but no arguments were provided
        A(int a): value(a) { }
        ^
bad_init.cpp:1:7: note: candidate constructor (the implicit copy constructor)
      not viable: requires 1 argument, but 0 were provided
class A {

bad_init.cpp:1:7: note: candidate constructor (the implicit move constructor)
      not viable: requires 1 argument, but 0 were provided
bad_init.cpp:8:36: note: in implicit initialization of array element 3 with
      omitted initializer
  bp = new A[3] { A(3), A(5), A(7) };
                                   ^
