#12532: boost::math::polynomial::evaluate does not work for the zero polynomial

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  math
  Version:  Boost 1.61.0      |   Severity:  Regression
 Keywords:                    |
------------------------------+-------------------------
 Due to a recent change in the representation of the zero polynomial, I
 think the evaluate function is broken for the zero polynomial.

 Currently if the evaluate method is called on a zero polynomial, it
 returns:
 {{{
 /usr/include/boost/math/tools/rational.hpp:191: U
 boost::math::tools::evaluate_polynomial(const T*, const U&, std::size_t)
 [with T = double; U = double; std::size_t = long unsigned int]: Assertion
 `count > 0' failed.
 }}}
