#9053: Infinite recursion assigning "const any" with GCC 4.8 in C++11 mode
--------------------------------+---------------------
 Reporter:  Di-an Jan <djan@…>  |      Owner:  nasonov
     Type:  Bugs                |     Status:  new
Milestone:  To Be Determined    |  Component:  any
  Version:  Boost 1.54.0        |   Severity:  Problem
 Keywords:                      |
--------------------------------+---------------------
 Infinite recursion assigning "`const any`" with GCC 4.8 in C++11 mode
 because "`boost::disable_if<boost::is_same<any&, ValueType> >`"
 is not triggered with a "`const any`".
 This leads to infinite recursion at run time with no compiler warnings.
 Happens with Boost 1.54.0 and boost-trunk.
