Сравнить итераторы, C ++

Is it possible to compare two iterators? A comparision using std::min

void change ( typename TList <Item *>::Type ::iterator it_begin, typename TList <Item*>::Type ::iterator it_end )
{
   ....
this->items.resize ( index );
   std::sort ( it_begin, std::min (it_end, it_begin += index - 1); //Compare two iterators, exception
....
}

throws the following exception:

Assertion failed: Vector iterators  incompatible... 

Is there any other way of the comparision?
