here is attached a simple reproducer.

I'm able to replicate the problem with 1.8.4 and 1.8.8 and 1.10.0 on OS X
10.10.5 (Yosemite) and Xcode 7.0.1. I'd suggest filing a bug at
bugreporter.apple.com with the information that clang provided in their output.
If there's a bug in the compiler, there's not much that we here a
Hi Gilles,
as for that, recompiling OpenMPI works, but causes no change here.

Hi Gilles,
yes MPI_Comm_compare can solve the issue, though one has to take care not to
pass MPI_COMM_NULL into that (according the MPICH documentation at least).
Even a simple modification can remove the issue:
"
...
MPI_Comm comm = MPI_COMM_NULL;
if (MPI_COMM_NULL == comm)
...
"

Tobias,
Btw, did you recompile ompi with this xcode ?
Iirc, we do similar comparisons in ompi itself

Tobias,
Fwiw, MPI_Comm_compare can be used to compare communicators.
Hopefully, this is also compiler friendly.

Hi all,
a wonderful puzzle for the OSX folks in your team (Reproducer attached):
Attached source file builds with Xcode 7.0.0, but fails since the release of
Xcode 7.0.1. I post it here since it results from an "if (MPI_COMM_NULL ==
MPI_COMM_SELF)". I am actually curious whether this is somehow
