     Type:  Bugs                      |      Status:  new               
Milestone:  Boost 1.50.0              |   Component:  functional/forward
  Version:  Boost Development Trunk   |    Severity:  Problem           
 Keywords:  c++11 decltype result_of  |  
--------------------------------------+-------------------------------------
 The clang c++11 test runner is showing failures with decltype-based
 result_of that do not happen with TR1-style result_of. See the results
 here (clang-cxx11 test runner):
