See

https://github.com/libMesh/libmesh/issues/1411

for some discussion.  We're still not sure how or even if it can be
generally fixed, but "use a newer compiler" is a possible workaround.
I'd be very interested to hear (preferably as another comment on that
issue, to keep it all together) whether or not a compiler upgrade
works for you too.
