Does anyone know of any weird behavior from allocators in VC 8.0? The Function library uses allocators when available, but the two tests of allocators (allocator_test and function_test) are failing on VC 8.0 (but not 7.1). From the config info, I see that BOOST_HAS_PARTIAL_STD_ALLOCATOR is defined but BOOST_NO_STD_ALLOCATOR is not (boost::function uses the latter).
The actual failure is here: http://tinyurl.com/dq3lh Could someone with access to VC 8.0 (beta 2, I guess) check to see what is happening here?
It's the first fallout from the recent type_traits changes, but it's a bug in the test case that's being exposed: Boost::function doesn't allocate any storage if the function object is stateless, and VC8 is now the first compiler to automatically detect stateless user-defined types via is_stateless, so Boost.Function assignment goes via: template<typename FunctionObj> void assign_to(FunctionObj, detail::function::stateless_function_obj_tag) which doesn't use an allocator at all, hence the failed tests. I think the solution is to fix the tests to use function objects that do have state. HTH, John.
