Thanks. I've made a patch with a similar idea:

This works, although the following alternative: template<class T> union function_buffer_ { // as before mutable T data; }; size_t const function_buffer_size = sizeof(function_buffer_<char>); typedef function_buffer_<char[function_buffer_size]> function_buffer; seems slightly more maintainable as it doesn't perform the size computation separately.
