Test program that causes the error.

The attached test fails with:


$ clang++ --std=gnu++14 -fopenmp clang_test.cc -o clang_test
clang_test.cc:20:23: error: reference to local variable 'x' declared in
enclosing function 'main'
                      x = y;
                      ^
clang_test.cc:9:9: note: in instantiation of function template specialization
'main()::(anonymous class)::operator()<int>' requested here
        f(v[i]);
        ^
clang_test.cc:16:5: note: in instantiation of function template specialization
'parallel_loop<std::vector<int, std::allocator<int> >, (lambda at

    ^
clang_test.cc:15:12: note: 'x' declared here
    double x;
           ^
1 error generated.


GCC compiles this fine, and I don't see why clang shouldn't as well.
