            Bug ID: 58940
           Summary: [C++11] Bogus "error: use of deleted function ..."
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ppluzhnikov at google dot com

Google ref: b/11457051

Using g++ (GCC) 4.9.0 20131028 (experimental)

g++ -c -std=c++11 t.cc
t.cc: In constructor 'constexpr B<int>::B()':
t.cc:7:32: error: use of deleted function 'A< <template-parameter-1-1>
>::A(const A< <template-parameter-1-1> >&) [with <template-parameter-1-1> =
int]'
 template < typename X > struct B
                                ^
t.cc:3:5: note: declared here
     A (A const &) = delete;
     ^
t.cc: At global scope:
t.cc:12:10: note: synthesized method 'constexpr B<int>::B()' first required
here
 B < int >b;
          ^

Compiles with Clang.
Probably same root cause as in PR58930. Test case:

// ---
template < typename > struct A
{
    A (A const &) = delete;
    A (int);
};

template < typename X > struct B
{
    A < X > a { 0 };
};

B < int >b;
// ---
