--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-12-19 20:14:08 UTC ---
I've just encountered this bug again when trying to replace

      constexpr unique_ptr(nullptr_t) noexcept
      : _M_t()
      { static_assert(!std::is_pointer<deleter_type>::value,
              "constructed with null function pointer deleter"); }

with

      constexpr unique_ptr(nullptr_t) noexcept : unique_ptr() { }

which causes a FAIL in the testsuite because now the constructor triggers the
static_assert in the default constructor which already FAILed earlier in the
file and so doesn't fire again.
