I have made a test build for 1.56 and would appreciate help in finding problems with it. [...] I’m looking for: [...] * build failures
With Visual C++ 2013 (tested with Update 3 RC), there is the following compiler error in debug mode: boost/smart_ptr/detail/array_allocator.hpp(174): error C2059: syntax error : 'constant' boost/smart_ptr/detail/array_allocator.hpp(187) : see reference to class template instantiation 'boost::detail::as_allocator' being compiled boost/smart_ptr/detail/array_allocator.hpp(182): error C2059: syntax error : 'constant' This is because of the following line in the Visual C++ headers in debug mode: #define free(p) _free_dbg(p, _NORMAL_BLOCK) Also, there is a new internal compiler error in boost/msm/back/dispatch_table.hpp, struct make_chain_row_from_map_entry.
