[mpich-discuss] memcpy argument memory ranges overlap

[Shouben Zhou]

I am new in this list and need some help.

I tried a bug report ( I think it is a bug related),  but failed to do 
so. So I am post my question here if some body can help.

I see a bug report #1006 reported same error I am getting.

One of my customers who is using CAM (the Community Atmosphere Model) is able 
to run it with MPI1 and MPI2-1.1,but fails with MPI2-1.2 and above

Here is the breif list of error
