在C 中使用upper_bound时崩溃

我有以下程序，该程序在上限呼叫中崩溃。我没有得到为什么发生崩溃的原因。我崩溃的任何原因。感谢您的帮助和时间。

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
enum quality { good = 0, bad, uncertain };
struct sValue {
   int time;
   int value;
   int qual;
};
struct CompareLowerBoundValueAndTime { 
    bool operator()( const sValue& v, int time ) const {
        return v.time < time;
    } 
    bool operator()( const sValue& v1, const sValue& v2 ) const { 
        return v1.time < v2.time; 
    }
    bool operator()( int time1, int time2 ) const { 
        return time1 < time2; 
    }   
    bool operator()( int time, const sValue& v ) const  { 
        return time < v.time;    
    } 
}; 
struct CompareUpperBoundValueAndTime { 
    bool operator()( const sValue& v, int time ) const {
        return v.time > time;
    } 
    bool operator()( const sValue& v1, const sValue& v2 ) const { 
        return v1.time > v2.time; 
    }
    bool operator()( int time1, int time2 ) const { 
        return time1 > time2; 
    }   
    bool operator()( int time, const sValue& v ) const  { 
        return time > v.time;    
    } 
};

    upper =  std::upper_bound(valueContainer.begin(), valueContainer.end(), time, CompareUpperBoundValueAndTime() ); // Crashing here.
    std::cout << "Lower bound: " << lower - valueContainer.begin() << std::endl;
    std::cout << "Upper bound: " << upper - valueContainer.begin() << std::endl;
   return lower - valueContainer.begin();
