#10669: Assertion failed in broadcast with BOOST_MPI_HOMOGENEOUS defined
------------------------------+---------------------
 Reporter:  sam.bateman@…     |      Owner:  troyer
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  mpi
  Version:  Boost 1.56.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 When running a program that does a very simple broadcast of a map<int,
 int> from the root proc (0) to another proc (1), I get this error:

 {{{
 Assertion failed: (position+l<=static_cast<int>(buffer_.size())), function
 load_impl, file
 /Users/sbateman/tmp/boost_mpi_test/boost_1_56_0/boost/mpi/detail/binary_buffer_iprimitive.hpp,
 line 110.
 }}}

 This only happens when I compile Boost with BOOST_MPI_HOMOGENEOUS defined
 (i.e., uncommented) in boost/mpi/config.hpp.  If I leave that line
 commented out, the program completes successfully.

 I've attached a source file (test.cpp) that reproduces this error.  I
 tested this on a Mac system with OS X 10.9.5 and compiler version:
 {{{
 Apple LLVM version 6.0 (clang-600.0.51) (based on LLVM 3.5svn)
 Target: x86_64-apple-darwin13.4.0
 }}}

 and also on a Linux system with compiler version:
 {{{
 gcc version 4.8.2 20131016 (Cray Inc.) (GCC)
 Target: x86_64-suse-linux
 }}}
