Hi,

The attached code is an example code that was working fine before I
made some changes!  I thought the changes I made were reasonable, but
that causes the code to not to work!  Please see the comments in the
code for more information.

The qeustion I have is not so much how to fix the code.

The question is, is this not an appropriate use for MPI_Type_extent?  

I could fix the code by calculating the offsets using the address of
operator.

Thanks!
