2nd call to partial_sort gives 'no match...' error, but 1st is OK.
Doesn't seem right.

#include <algorithm>
#include <vector>

template<typename vector_t>
 struct Sort_Func2  {
  vector_t const& mag;
  Sort_Func2 (vector_t const& _mag) : mag (_mag) {}
  bool operator() (int a, int b) const { return mag [a] < mag [b]; }
};

template<typename vector_t>
void F (vector_t const& v) {
  struct Sort_Func {
    vector_t const& mag;
    Sort_Func (vector_t const& _mag) : mag (_mag) {}
    bool operator() (int a, int b) const { return mag [a] < mag [b]; }
  };

  std::vector<int> indexes (v.size());
  std::partial_sort (indexes.begin(), indexes.begin()+2, indexes.end(),
Sort_Func2<vector_t> (v));
  std::partial_sort (indexes.begin(), indexes.begin()+2, indexes.end(),
Sort_Func (v));
}

int main() {
  std::vector<int> v;
  F (v);
}
