[Mpi3-rma] Conflicting PUT/GET accesses clarification

[Pavan Balaji]

Page 339 lines 21-24 of MPI-2.2 states the following:

"It is erroneous to have concurrent confl icting accesses to the same 
memory location in a window; if a location is updated by a put or 
accumulate operation, then this location cannot be accessed by a load or 
another RMA operation until the updating operation has completed at the 
target."

What does this mean when I do PUT with a datatype with overlapping 
buffers? Is that valid or erroneous?
