12789	"Instantiating bimap with all three ""additional"" template parameter fails to compile."	jonathan.haigh@…	Matias Capeletto	"The following test program fails to compile.

The compile error from g++ 4.9.2 starts with:

Boost thinks my with_info parameter is an allocator! The full compiler output will be attached, but I think this is enough to see the problem.

It looks like the cause is the case_SHA struct in boost/bimap/detail/manage_additional_parameters that deals with the case when all three additional template parameters are given to bimap:

{{{#!c++
template< class AP1, class AP2, class AP3 >
struct manage_additional_parameters
{
...
    struct case_SHA
    {
        typedef AP1 set_type_of_relation;
        typedef AP2 allocator;
        typedef BOOST_DEDUCED_TYPENAME AP2::value_type additional_info;
    };
}}}
AP2 is used for both the allocator type and the additional_info type. I think allocator should be typedefed to AP3, not AP2."	Bugs	new	To Be Determined	bimap	Boost 1.55.0	Problem
