使用 gsl_root_fsolver_root()求解器求解四次方程根

根据官网例程写的解算器，win10+vs2005+gsl1.8 求解四方方程的根 定义了根的上下限，可以得到唯一解 放在工程中实时在线求解的时候不定期会报内存泄漏:Object dump complete.，有遇到相同情况的吗？ 检查了下发现 gsl 版本较低，更新成 2.4 版本后同样的问题

double a = ((struct rparams *) params)->a;

double b = ((struct rparams *) params)->b;

double c = ((struct rparams *) params)->c;

double d = ((struct rparams *) params)->d;

double e = ((struct rparams *) params)->e;


double f = (1.0 / 4.0)*c*pow(x, 4) + (1.0 / 3.0)*b*pow(x, 3) + (1.0 / 2.0)*a*pow(x, 2) + d*x - e;

return f;
