[Bug c++/37204] New: reinterpret_cast<T&&>(v) incorrectly yields an lvalue

[gcc-bugzilla at contacts dot eelis dot net]

Consider:

  #include <iostream>
  void f(int &) { std::cout << "lvalue\n"; }
  void f(int &&) { std::cout << "rvalue\n"; }
  int main() { int x(3); f(reinterpret_cast<int&&>(x)); }

This /should/ output "rvalue", but it outputs "lvalue" instead (when compiled
with -std=c++0x).

In 5.2.10p1, n2691 (the most recent C++0x draft) states w.r.t.
reinterpret_cast<T>(v):

  "If T is an lvalue reference type, the result is an lvalue; otherwise, the
result is an rvalue"
