This has been a known problem for a very long time, and the work around is quite simple. Replace

reinterpret_cast(&in_buffer.data)->~Functor();

with

functor_type* p = reinterpret_cast(&in_buffer.data); p->~Functor();

Note however that this replacement causes a warning on MSVC ('p' not used), so it needs to be conditional, as in

https://svn.boost.org/trac/boost/changeset/69251

I have run my patch on MSVC (8, 9, and 10) and GCC, and I do not recall seeing warnings from MSVC. Isn't p being used to call the destructor?

Is there a ticket?

I do not know. Respectfully, Justin
