Assertion failed in broadcast with BOOST_MPI_HOMOGENEOUS defined

[sam.bateman@…]

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
