Hi,
I just started testing Boost 1.34.1 and have found this piece of code produces a warning, which was not present in Boost 1.33.1:
...
It seems to pick this specialisation: template< class M, class T > struct add_cref< M T::*, 1 > { typedef M const & type; //bind.hpp(1575) };
When I would have thought this one more appropriate:
template< class R, class T > struct add_cref< R (T::*) (), 1 > { typedef void type; // bind.hpp(1580) };
Any ideas?
None. We've reported this to Microsoft and they have (after much deliberation) classified it as a bug, but apparently a fix would be non-trivial and I don't know whether they plan to ever issue one for the MSVC 8 line.
The warning is harmless, as the wrong specialization is only used in a return type in an overload that isn't chosen (the only purpose of this specific specialization is to avoid the warning).
OK, thanks. Ben
