This is not likely to be the same bug. N3276 is about decltype causing
the recursive instantiation of a class template -- unconditionally. In
this case, a call to the back function succeeds if you pass fewer
parameters, but fails with more. Seems to merely indicate an inefficient
algorithm, not a fundamental problem.
