Martin, Ok. I know where the problem is for __has_nothrow_copy and assign.
Thanks.

Similarly to (but not exactly the same as) the template ctor in bug 36871,
gcc 4.3.0 trips up on class with a throwing vararg ctor (regardless of the
number of arguments):

This also fails. Seems that the combination of a copy ctor and template ctor
(even non-throwing) trips the compiler up.

The program below is expected to run with no assertions (template ctor
is not a copy ctor). Instead, when compiled with gcc 4.3.0, it aborts.
