Thank you, it's very good news. If the issue has been fixed, then does
it mean that v1.3.2 will allow to run applications compiled with v1.2.9?
Or is it starting with v1.3.2 and subsequent releases will be backward
compatible with each other?

That being said, we have fixed this issue and expect to support binary
compatibility between Open MPI releases starting with v1.3.2 (v1.3.1
should be released soon; we're aiming for v1.3.2 towards the beginning
of next month).

Hello,
We have a number of applications built with Open MPI 1.2 in a shared
multi-user environment. The Open MPI library upgrade has been always
transparent and painless within the v1.2 branch. Now we would like to
switch to Open MPI 1.3 as seamlessly. However, an application built with
ompi v1.2 will not run with the 1.3 library; the typical error messages
are given below. Apparently, the type ompi_communicator_t has changed.
Symbol `ompi_mpi_comm_null' has different size in shared object,
consider re-linking
Symbol `ompi_mpi_comm_world' has different size in shared object,
consider re-linking
Do I have to rebuild all the applications with Open MPI 1.3?
Is there a better way to do a smooth upgrade?
Thank you.
