Comment (by akrzemi1):

 Replying to [comment:1 johnmaddock]:
 > I don't know how to fix this - those GCC versions fail inside the
 noexcept expression when the class being tested has a private assignment
 operator or copy constructor.  There appear to be no compiler intrinsics
 available for those GCC versions either.  So I'm stuck.

 I understand the difficulty. Is it possible to isolate the offending
 compiler versions and provide a trivial definition of the trait for them?
 I can see it is not easy as the traits seam to work for other testers with
 GCC 4.6.

 > BTW I don't believe this ever worked, but I could be wrong?

 I cannot be sure. But I thing these errors weren't there in
 Boost.Optional. Perhaps these testers are new.
