Thanks for your reply.
I think its the best to give you the versions of the implementations I use
LAM MPI 7.1.5
As you see in my program code, I use MPI_Win_get_attr to show the size of the window. Program crashes here. So I presume something went wrong at the WIN_Create call.
I can comment out the MPI_Win_get_attr call, but then MPI_Get reads wrong data. I presume It reads somewhere outside the window because printf will show something like 2478000

I'll let Nathan/others comment on the correctness of your program.
What version of Open MPI are you using? Be sure to use the latest to get the most correct one-sided implementation.
Also, as one of the prior LAM/MPI developers, I must plead with you to stop using LAM/MPI. We abandoned it many years ago in favor of Open MPI. :-)
