Hi Joaquín,

I was out of office several days. Sorry.
So, I send my reply today.

I don't have permissions to change something under /boost.

But here other test I did:

--- file foo19.cpp ---
struct Bar
{
    virtual ~Bar(){}
};

int main()
{
        
        const Bar* p1 = new Bar;	
        const_cast<Bar*>(p1)->~Bar();	// No problem   
        
        const Bar* p2 = new Bar;	
        p2->~Bar();	// line 13: Error: Non-const function Bar::__SLIP.DELETER__A() called for const object.
        
        return 0;
}
-------------------

Compilation: 
%CC -m64 -library=stlport4 foo19.cpp

OK, seems like the bug we were after, if only in a slightly different guise
(deleting a const T* works, but directly calling ~T() on a const object
does not).

Alex, can you do the following? Please try replacing the
/boost/detail/allocator_utilities.hpp file in your local Boost copy
with the attached file and rebuild the multi_index_container code
that was failing. Does this fix it? If so, I'll commit this version into th=
trunk so that it'll be available in Boost 1.38 (though you can use it
now with your local Boost copy, of course).
