I've responded over on SO as well, but the problem is that
boost::numeric::interval
is instantiating
std::complex with a user-defined type, and the standard gives no assurances
that this will work.

[complex.numbers]/2 says:

The effect of instantiating the template complex for any type other than
> float, double, or long double is unspecified.
