MPI_Info_set crashes

Here is a small section of my test code

use mpi

.......

call mpi_init(info)
comm = mpi_comm_world

call MPI_COMM_SIZE(comm, nproc, info)

call MPI_COMM_RANK(comm, node_me, info)

len0 = 300
len1 = int8(len0)*10*100
size = len1
disp_unit = 8
size = size*disp_unit

call MPI_Info_create(info_nc,ierr)

call MPI_Info_set(info_nc, "alloc_shared_noncontig" , ".true." ,ierr)

call MPI_Win_allocate_shared(size, disp_unit, info_nc, &
comm, baseptr, win,ierr)

.......

It always crashes when calling subroutine MPI_Info_set with a message as follows

Unhandled exception at 0x000007FEE07FDA6E (impi.dll)

I used the lastest intel fortran compiler 17.0 and intel mpi library 2017 (2017.1.143). It was tested on MS Windows 7.

Thanks.

Can you provide a full reproducer? When I put what you have provided into a small code, it is working correctly.
