This is a definite error (I replicated it with a trivial C equivalent
of your python program) -- I'll file a bug.
Thanks for reporting it, Lisdandro!

In current ompi-trunk (svn up'ed and built a few minutes ago), a

Is this change intentional or is it a regression?
$ cat typedup.py
from mpi4py import MPI
t = MPI.INT.Dup()
t.Free()
$ python typedup.py
