[boost] [array] failures in c++11 mode

hi, r82834 seems to break compilation of boost.array when compiled in c++11 mode: ../../../boost/array.hpp:131:9: error: body of constexpr function ‘constexpr const T& boost::array<T, N>::operator[](boost::array<T, N>::size_type) const [with T = boost::heap::detail::skew_heap_node<q_tester, false>*; long unsigned int N = 2ul; boost::array<T, N>::const_reference = boost::heap::detail::skew_heap_node<q_tester, false>* const&; boost::array<T, N>::size_type = long unsigned int]’ not a return-statement the boost.heap testsuite exposes this failure: http://www.boost.org/development/tests/trunk/developer/output/Sandia-gcc-4-7... thnx, tim
