#8651: Uneeded usage of namespace causes problems for the compiler
------------------------------+---------------------------------------------
 Reporter: anonymous | Owner: ebf

Milestone: To Be Determined | Component: variant
  Version: Boost 1.53.0 | Severity: Cosmetic

 using debian sid
 Package: libboost1.53-dev
 Source: boost1.53
 Version: 1.53.0-5

 The gcc compiler crashes using some options when compiling (dump
 translation unit)

 Here is a small change to work around the crash :

 namespace boost {

     namespace detail { namespace variant {
         struct variant_hasher: public //boost::
         static_visitor<std::size_t> {
             template <class T>
             std::size_t operator()(T const& val) const {
               //using namespace boost;
                 hash<T> hasher;
                 return hasher(val);
             }
         };
     }}
 }

 It is the uneeded namespace usage that causes the problem.
