Hello,

We are getting seg faults at run time on MPI_CART_CREATE() when
using openmpi-1.1.2 built with the intel compilers. I have included
all versions, code and messages bellow. I know there were problems
in the past, and dug around the archives but didn't find this any
place. Has anyone else seen this problem?

The message is like so:

[brockp_at_nyxtest1 bagci]$ mpirun -np 1 ./a.out
Signal:11 info.si_errno:0(Success) si_code:2(SEGV_ACCERR)

*** End of error message ***

ifort is version 9.1.037
icc icpc are version 9.1.043

This problem does not happen with pgi compilers. (version 6.1)
Both were done em64t systems (xeon 5160's)

Here is the code sample that fails.

program cart
include 'mpif.h'

call MPI_INIT(ierr);
call MPI_COMM_SIZE(MPI_COMM_WORLD, numprocs, ierr)
call MPI_COMM_RANK(MPI_COMM_WORLD, my_world_id, ierr)
call MPI_CART_CREATE(MPI_COMM_WORLD, 1, numprocs, .false., .true.,
ITER_COMM, ierr)
call MPI_COMM_RANK(ITER_COMM,myid, ierr)

call MPI_FINALIZE(ierr)
end
