Milestone:  To Be Determined      |   Component:  math       
  Version:  Boost 1.52.0          |    Severity:  Problem    
 Keywords:                        |  
----------------------------------+-----------------------------------------
 On line 200 of boost/math/tools/toms748_solve.hpp, the code should be
 checking whether the coefficient 'A' of the quadratic polynomial is zero
 before giving up and calling secant_interpolate, not the variable 'a',
 which is the lower bound of the bracket.
