Bolt1.2: std::partial sum is having compilation issues when we used with UDD by calling transform_iterator.

CODE:

int get_global_id(int i);

int global_id;

BOLT_FUNCTOR(UDD_trans, struct UDD_trans { int i ; float f ;

UDD_trans ()  
    {
    }; 

UDD_trans (int val1)  
    {
        i =  val1 ;

    }; 
bool operator == (const UDD_trans& other) const {
    return ((i+f) == (other.i+other.f));
}

UDD_trans operator() ()  const 
    { 
        UDD_trans temp ;
        temp.i =  get_global_id(0);
        return temp ;
        //return get_global_id(0); 
    }

}; );

int get_global_id(int i) { return global_id++; }

BOLT_FUNCTOR(add_UDD, struct add_UDD { int operator() (const UDD_trans x) const { return x.i + 3; } typedef int result_type; }; );

BOLT_TEMPLATE_REGISTER_NEW_ITERATOR( bolt::cl::device_vector, int, UDD_trans); BOLT_TEMPLATE_REGISTER_NEW_TRANSFORM_ITERATOR( bolt::cl::transform_iterator, add_UDD, UDD_trans);

int main() {

int length =  5;

std::vector< UDD_trans > svInVec1( length ); 

std::vector< int > stlOut(length);

add_UDD add1;
UDD_trans gen_udd(0) ;

// ADD
