[Boost-users] boost::math::cyl_bessel_j_zero: few NaN

double order = (double)lcur + 0.5;
unsigned int n_zeros;
vector<double> zeros;
boost::math::cyl_bessel_j_zero(order,1,n_zeros, back_inserter(zeros));

I'am running Boost 1.59 on Mac OS X Maverick

for lcur = 0, I expect zeros filed with Pi, 2 Pi, 3Pi.... but the first 
two zeros I get NaN
I get also other nan as for the 2nd zeros for lcur=1

Have you experienced such problem or I have a memory leak somewhere ?

Thanks
