Description
In the function saveRecvBuf, MPI_Unpack is used to read a std::size_t value into `size' so it needs the right type. Using an int causes other local variables to be overwritten by the function call:
352 MPI_Unpack(recvBuf, bufferSize, &pos, &size, 1, MPITraitsstd::size_t::getType(), comm);
A patch to change the type of size from int to std::size_t is attached.
Thanks to Jö for helping to find this bug.
