Subject: [OMPI devel] Cannot Free() a datatype created with Dup() or Create_resized()
From: Lisandro Dalcin (dalcinl_at_[hidden])
Date: 2009-08-31 17:55:23


In current ompi-trunk (svn up'ed and built a few minutes ago), a
Free() from a datatype obtained with Dup() or Create_resized() from a
predefined datatype is failing with ERR_TYPE...

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
Traceback (most recent call last):
  File "typedup.py", line 3, in <module>
    t.Free()
  File "Datatype.pyx", line 328, in mpi4py.MPI.Datatype.Free
(src/mpi4py.MPI.c:28632)
mpi4py.MPI.Exception: MPI_ERR_TYPE: invalid datatype
