https://svn.boost.org/trac10/ticket/10669 <p> When running a program that does a very simple broadcast of a map&lt;int, int&gt; from the root proc (0) to another proc (1), I get this error: </p> <pre class="wiki">Assertion failed: (position+l&lt;=static_cast&lt;int&gt;(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. </pre><p> 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. </p> <p> I've attached a source file (test.cpp) that reproduces this error.
