c++ opencv randu function throws 'Integer division by zero'

I'm trying to fill a cv::Mat with random numbers.

cv::Mat mat(100, 100, CV_8UC4);
cv::randu(mat, cv::Scalar(0), cv::Scalar(256));

The above code works fine, as long as I keep the scalars exactly as they are. Changing 0 and 256 to any other values will cause an Integer division by zero exception on the call to randu. Can anyone explain to me why? I'm using opencv3.

it looks like a bug in opencv<3.4.

please update to the latest opencv (you can still stay with opencv3)
