I don't think a ticket or PR was filed for this. I was able to reproduce on
a Power8 machine, and filed the issue below:
https://github.com/open-mpi/ompi/issues/1854
Nathan I added you to the ticket since it sounded like you had an idea
where the problem was.

Josh,
Big-endian Power7:
$ xlc -qversion
IBM XL C/C++ for Linux, V13.1
Version: 13.01..
$ export OBJECT_MODE=64
$ [...]/configure -prefix=[] --enable-debug \
CC=xlc CFLAGS="-q64" --with-wrapper-cflags="-q64" \
CXX=xlC CXXFLAGS="-q64" --with-wrapper-cxxflags="-q64"
Paul,
What was the configure string you used for this?
We have a Jenkins CI mechanism for XL, but it is using XLC 13.1.3 on that
system and we haven't been runing 'make check'. I have another system that
has XLC 13.1.2 that I can test on as well. I'm not sure if I'll be able to
fix without Nathan
The issue reported in
https://www.open-mpi.org/community/lists/devel/2016/06/19107.php is still
present on both my little-endian Power8 and big-endian Power7 systems.
I know Nathan had been working on this, but I've lost track of the issue
and/or pr number(s).
