            Bug ID: 21493
           Summary: Compilation error when initializing in an agreggate
                    containing a deleted copy constructor using
                    initializer list from  a template function
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11

This valid code:

struct X  { X(int);  X(const X&) = delete; };
struct A { X v; };
template <typename T> void id() { A s{ {0 } }; }
int main() { id<A>(); }

does not compile:

test.cc:3:43: error: call to deleted constructor of 'X'
template <typename T> void id() {  A s  { {0 }  }; }
                                          ^~~~
test.cc:4:14: note: in instantiation of function template specialization
'id<A>' requested here
int main() { id<A>(); }
             ^
test.cc:1:22: note: 'X' has been explicitly marked deleted here
struct X  { X(int);  X(const X&) = delete; };
