            Bug ID: 35034
           Summary: An R-value to L-value reference binding in a templated
                    constructor
           Product: clang
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org

A really nasty bug:

template<typename T>
struct data {

  template<typename U>
  data( U && value ) : _value{ T( std::forward<U>( value ) ) } {}

  T _value;
};

data< int& > d{ 10 }; //okay on Clang, not okay on GCC & MSVC

The initial intent for the code was to avoid strict init rules for uniform
initialization in a converting constructor.
