Hi all,

IMO test/mpi/comm/cmfree.c in mpich2-1.0.5p4 there is one MPI_Comm_free 
missing.

On line 29, there is a `MPI_Comm_dup(MPI_COMM_WORLD,&comm)`. However the 
comm that gets created here is only freed if 'rank == dest' on line 54. 
In all ranks that are not equal to 'dest', the communicator is never freed.

Of course, this is not an error (just a leak) but wanted to let you know 
nevertheless,

toon
