Gilles, This is on Mellanox's own system where /opt/mellanox/hcoll was updates Aug 2. This problem also did not occur unless I build libmpi statically. A run of "mpirun -mca coll ^ml -np 2 examples/ring_c" still crashes. So, I really don't know if this is the same issue, but suspect that it is not.
