Hi Brian,
I filed a bug several months ago about derived datatypes in RMA:
https://svn.open-mpi.org/trac/ompi/ticket/2656
Could this be the same issue?

Hello Brian,
You do not have to be sorry. my code was not that clear.
My Open MPI version is 1.6, the network is Ethernet.
About the MPI_Alloc_mem, I tried with malloc also, but was getting the same
seg-fault.
Thanks,
Ziaul

You're right, I totally misread the code, sorry about that. What version
of Open MPI are you using and over what network?
As an aside, there's no point in using MPI_ALLOC_MEM for the displacement
arrays. MPI_ALLOC_MEM is really only advantageous for allocating
communication buffers. Si
indices are for derived datatype. in this case indexed datatype.

Hello Brian,
Actually, I am not modifying the local communication buffer that contains
the data. I am modifying the the buffer that contains the indices of the
data buffer(source_disp and target_disp).
in MPICH2 this is not a problem. I am not sure about Open MPI.
Thanks,

Ziaul -
Your program is erroneous; you can not modify the local communication
buffer of an MPI_ACCUMULATE call until after the next synchronization call
(Section 11.3 of MPI 2.2). In your example, that would be after the
MPI_FENCE call following the call to MPI_ACCUMULATE.

Hello,
I am not sure, if my code is correct according to Open MPI(v1.6). the code
is given as follows, I am doing MPI one-sided communication inside a
function - data_transfer. this function is being called inside a fence
epoch. inside data_transfer, I am allocating memory for non-contiguous
data,
