[type_traits] is_list_constructible regression failures
Hello all,
I noticed the following failure in Boost.TypeTraits regression tests
on GCC 4.6 C++11. Any idea why this is failing?

There's something different about that tester - there are several gcc-4.6 test runners in the matrix and they're all passing is_list_constructible_test bar that one. What/why the difference is there I have no idea :( John.

I am asking because a couple of Boost.Contract tests that #include
fail with the same Boost.TypeTraits error on this compiler. Thanks. --Lorenzo

I don't think the error is limited to that tester.
I get the same Boost.TypeTraits error in 2 Boost.Contract tests on
that compiler/plaform. All these tests do is to #include

It's possible that this is the only 4.6 tester that uses -std=c++0x. is_list_constructible has #if defined(BOOST_NO_SFINAE_EXPR) || defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES) || defined(BOOST_NO_CXX11_DECLTYPE) || defined(BOOST_NO_CXX11_UNIFIED_INITIALIZATION_SYNTAX) || defined(BOOST_NO_CXX11_FUNCTION_TEMPLATE_DEFAULT_ARGS) but that's apparently not enough to disable it on 4.6. (It's probably the derivation from `decltype` that confuses the compiler.) Travis does have 4.4 and 4.6, so we may want to add these to Type Traits. https://github.com/boostorg/smart_ptr/commit/77a35856c6f51176dc15c00f0e4ca95...
