Comment (by Roland Haas):

Ok, it having been retired would have been too simple.

Unfortunately it is not dead code and is used (though not in the ET right now), please see https://bitbucket.org/einsteintoolkit/tickets/issues/2115/supermike-ii-fails-to-compile#comment-52788391 .

Given that this compiles on quite a number of other clusters (with Intel compilers) I wonder what makes it fail on Spruce Knob and the previous Mike setup.

I did a quick test on BlueWaters with the intel 16 compiler there. Since the failing code is:

class foo {
  foo(foo&&) = default;
};

I created such a file and tried compiling it with icpc. All is well if I use the default settings:

icpc -c -std=c++11 foo.cc

However if instead I force icpc to use an old gcc version (4.3 in my case) then I get:

icpc -c -std=c++11 -gcc-name=/usr/bin/gcc-4.3 foo.cc
foo.cc(2): error: invalid type for defaulted constructor
    foo(foo&&) = default;
    ^

compilation aborted for foo.cc (code 2)
