push :: sort对某些值进行了错误排序

Question

I have some objects I want to sort on a host_vector, These objects have a < Operator defined, which compares the Id (a integer) of the objects. The vector contains pointers to the objects.

If I perform thrust::sort(object_vector.begin(),object_vector.end()); and then iterate through the vector to print the Id's I get:
48, 49, 0, 1, [..], 47, 50, [..]

If I perform std::sort(object_vector.begin(),object_vector.end()); I get the Id's in order. I have no clue why these two values are out of order (they are always the same for the same number of objects).
The objects according to this Id's have nothing special.

stable_sort doesn't change anything. Sorting a vector with the Id's works. Operators:

bool operator<(MultiLegBase* other){return (this->getID()<other->getID());}
bool operator==(MultiLegBase* other){return this->getID()==other->getID();}
bool operator>(MultiLegBase* other){return this->getID()>other->getID();}
virtual unsigned int const getID(return m_Id;)

Answer 1

I looked again on my operators and got what is wrong. The this->getID() construct fails. Because operator>() , is not called with two pointer arguments (as far as I understand). I solved it with an functor: [..] bool operator()(Multibaseleg* M,Multibaseleg* N){return (M->getID()<N->getID());}[..]
