Ok.
I have built gcc 4.7.2 and run the array tests.
I see the failure that you reported.
I also see a gcc crash in the test "array_constexpr":

        darwin.compile.c++ ../../../bin.v2/libs/array/test/array_constexpr.test/darwin-11/debug/array_constexpr.o
        array_constexpr.cpp: In member function 'void test_main::test_method()':
        array_constexpr.cpp:32:36:   in constexpr expansion of 'arr.boost::array<T, N>::at<int, 10ul>(3ul)'
        array_constexpr.cpp:32:36: internal compiler error: in adjust_temp_type, at cp/semantics.c:6400
        Please submit a full bug report,
        with preprocessed source if appropriate.
        See <http://gcc.gnu.org/bugs.html> for instructions.

More as I find it out. ;-)
