     Type:  Bugs          |      Status:  new          
Milestone:  Boost 1.36.0  |   Component:  concept_check
  Version:  Boost 1.35.0  |    Severity:  Problem      
 Keywords:                |  
--------------------------+-------------------------------------------------
 after upgrading to gcc 4.2.3 the following snippet fails to compile

 {{{
 #include <boost/concept_check.hpp>
 struct MyVisitor{};
 namespace test{ struct MyVisitor{};}
 namespace{ struct MyVisitorAnon{};}

 int main(){
   using namespace boost;
   function_requires<CopyConstructible<MyVisitor> >();
   function_requires<CopyConstructible<test::MyVisitor> >();
   function_requires<CopyConstructible<MyVisitorAnon> >(); //this
 linebreaks the build
   return 0;
 }
 }}}
 The error message is attached.
 Is this a problem of gcc or concept_check?
