#12493: Compile error in boost::intrusive with Sun compiler 12.4
------------------------------+------------------------
 Reporter:  kilian.kilger@…   |      Owner:  igaztanaga
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  intrusive
  Version:  Boost 1.58.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------
 When trying to compile the unit tests in boost::container, I get compile
 errors in boost/intrusive/detail/to_raw_pointer.hpp on Sun with the 12.4
 Sun Studio compiler in non-C++11 mode when using the ancient STLport 4.5.

 "/boost/intrusive/detail/to_raw_pointer.hpp", line 41: Error: Variable p
 of type void*const is not a structure.
 "/boost/container/detail/multiallocation_chain.hpp", line 66:     Where,
 temwhileinst: While instantiating
 "boost::intrusive::detail::to_raw_pointer<void*>(void*const&)".
 "/boost/boost/container/detail/multiallocation_chain.hpp", line 66:
 Where, teminstend: Instantiated from non-template code.

 For me it seems that the Sun compiler picks the wrong overload here. Why
 is the code there not "disambiguated" via boost::enable_if?

 The following code seems to work:

 template<class Pointer>
 inline typename boost::intrusive::pointer_element<Pointer>::type*
 to_raw_pointer(const Pointer &p, typename
 boost::disable_if<boost::is_pointer<Pointer> >::type * = 0)
 { ... }

 At least, the unit tests are running.

 The code in this file did not change in this regards in Boost 1.61.
