Looks the bug was reported to Ubuntu almost two years ago but still Unassigned,

I don't know how many hours of people's time were wasted on re-discovering this

Ah, got it.
Yes, if I compile with --enable-heterogeneous, the I can replicate the problem.
Looks like we opted not to fix this problem in the 2.1.x series. I'll update

I am able to replicate the issue on a stock Ubuntu 18.04 install with their
Open MPI package.
But if I compile my own Open MPI 2.1.1, it works fine.
Also, if I compile my own Open MPI 2.1.6, it works fine.
I filed a bug at Ubuntu about this:
$ aptitude versions libopenmpi-dev
Package libopenmpi-dev:
i 2.1.1-8 bionic 500
Package libopenmpi-dev:i386:
p 2.1.1-8 bionic 500
$ sudo apt-get install libopenmpi-dev=2.1.6
Reading package lists... Done
Building dependency tree
Reading state information...
Does the bug exist in Open MPI v2.1.6?

Hello,
I met a bug with OpenMPI 2.1.1 distributed in the latest Ubuntu 18.04.2 LTS.
It happens with self to self send/recv using MPI_ANY_SOURCE for message
matching. See the attached test code. You can reproduce it even with one
process.
It is a severe bug. Since this Ubuntu is widely
