Hi Gus,
Yes I did, with the same result on each process. Actually the problem
was spotted on a real code although I just posted the minimal version.

Hi Alain
Have you tried this?
mpiexec -np 2 ./a.out
Note: mpicc to compile, mpiexec to execute.
I hope this helps,

I tried to goole the issue, and saw something regarding an old vectorization
bug with intel compiler, but that was a lonng time ago and seemed to be fixed
for 1.6.x.
Also, "make check" went fine ???
Any idea ?
Cheers
