5015,ibeta_inv_imp handling cases when (q == 0 or p == 0) or (a == 1 and b == 1),agribov_no_s_p_a_m@…,John Maddock,"File: boost\math\special_functions\detail\ibeta_inverse.hpp
Function: T ibeta_inv_imp(T a, T b, T p, T q, const Policy& pol, T* py)
Line: 480-503.
When ((q or p is equal to 0) or (a and b equal to 1))
and invert is true the return value is not reverted.
It can be fixed by placing these checks before
   if(a == 0.5f)
   {
      std::swap(a, b);
      std::swap(p, q);
      invert = !invert;
   }
