I'm not sure why the following test-class produces this error: "MPI_Recv:
MPI_ERR_TRUNCATE: message truncated"
If the std::map has only a single element (ie I remove one of the
test[].push_back() lines) the error does not occur. Can someone verify that
this is indeed a bug and not just novice misuse of the library?
Thanks,
Tim
