You do not explicitly instantiate the static member 'Test::out', so the compiler provides an implicit instantiation which is placed at the end of the file, so it is initialized after the variable 'a'. See http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#993 which clarified this result is permitted.
