Hi,

I'm using a few day old RC_1_34_0 from cvs.

In boost\function\function_base.hpp I get a warning message that is quite annoying so I went in to remove it.

The thing is I don't understand what it is complaining about. It gives this warning message:

boost/function/function_base.hpp(287) : warning C4189: 'out_functor' : local variable is initialized but not referenced

But the code is:

functor_type* out_functor = reinterpret_cast(&out_buffer.data); // Some compilers (Borland, vc6, ...) are unhappy with ~functor_type. out_functor->~Functor();

which looks a lot like it is referencing out_functor to me.. can this warning be disabled

I think that changing to

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

can fix it.

Yes that removes the warning it'd be great if that could be patched into RC_1_34_0 & HEAD.

Committed to both. If it causes any problems on RC_1_34_0, I'll back out this patch and using a #pragma warning disable instead. Doug
