Fair enough. I don't think I realized nixOS was a Linux distro.
That being said, every time I think I understand linkers, I find

Tyson,
thanks for taking the time to do some more tests.
This is really a bug in Open MPI, and unlike what I thought earlier,
there are still
some abstraction violations here and there related to ompio.
I filed https://github.com/open-mpi/ompi/pull/5263 in order to address them

Assuming this is a fresh install, and at first glance, there is an
abstraction violation here
fcoll/individual should not directly call a function of io/ompio
NixOS linker might be very strict and that could explain why this
mistake was unnoticed until now.
Would you mind giving the latest Ope
Before digging any deeper, did you perchance install multiple versions of Open
MPI into the same prefix?
If so, remember that Open MPI installs lots of plugins. The exact set of
plugins changes every release. So if you install version A.B.C in to
/opt/openmpi, and then install version X.Y.Z i
This email starts out talking about version 1.10.7 to give a complete

although to a lesser extent though, and am asking for help on that
release.
