Comment:

 This is not a bug.  The value_type of the
 iterator is assumed to be a 32 bit integer, while
 RealType is usually a double.  The loop is needed
 because RealType may have more bits of precision than
 the iterator's value_type.  Thus, more than one element
 of the input range may be needed to initialize a single
 element of the state.  Therefore the iterator needs
 to be incremented in the inner loop.
