boost/intrusive/detail/has_member_function_callable_with.hpp: inheriting from a const class

Reported by: 1czajnik@… Owned by: igaztanaga
Milestone: To Be Determined Component: intrusive
Version: Boost 1.52.0 Severity: Problem
Keywords: Cc: 1czajnik@…



I tried to use a boost::container::vector with a Texas Instruments compiler, and I got an error pointing to line 88 of <boost/intrusive/detail/has_member_function_callable_with.hpp> "Invalid base class", with Type=const std::allocator<something>"

Here's the context:

      template <typename Type>
         struct BaseMixin

         struct Base : public Type, public BaseMixin { Base(); }; // <-- line 88

The problem seems to be the constness of Type. Here's a simplified example:

struct X {};

template < class T >
struct Y : T { Y() {} };

int main()
    Y<const X> y;

The above example compiles fine with Linux gcc version 4.5.4, and MinGW 4.5.0, but fails with my TI compiler.

For now, my workaround is:

struct Base : public ::boost::remove_cv<Type>::type, public BaseMixin { Base(); }; // <-- line 88
