#11223: Context does not properly check support for std::integer_sequence
------------------------------+---------------------

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  context
  Version:  Boost 1.58.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 When I build Boost 1.58 with C++11 support on GCC 4.8.2, it fails to build
 the context library. This is due to the library attempting to use
 std::index_sequence:

 {{{
 In file included from libs/context/src/execution_context.cpp:11:0:
 ./boost/context/execution_context.hpp:202:52: error: ‘std::index_sequence’
 has not been declared
 }}}

 std::index_sequence is a feature only available in C++14.

 A workaround would be:
 1. First build a C++11-enabled Boost using the --without-context option
 2. Build the missing context library using --with-context, making sure
 that -std=c++11 is NOT added to the cxxflags

 My platform is GCC 4.8.2, x86_64-linux-gnu, Linux Mint 17 (based on Ubuntu
 14.04)
