Running a normal peptide MD simulation with
mdrun -seppot on two cores gives:

[rschulz-laptop:32326] * An error occurred in MPI_Bcast
[rschulz-laptop:32326]
on communicator MPI_COMM_WORLD
[rschulz-laptop:32326]
MPI_ERR_TRUNCATE: message truncated
[rschulz-laptop:32326] *
MPI_ERRORS_ARE_FATAL (your MPI job will now abort)

This is with current GIT HEAD and with 4.0.5.
