不需要函数间跳转，函数内跳转就可以。

#include <iostream>
#include <stack>
using namespace std;
int main()    {
    unsigned int label1,label2;
    stack<unsigned int> stk;
    stk.push(label1);
    stk.push(label2);
    while(!stk.empty()) {
        unsigned int to=stk.top();
        stk.pop();
        goto to;
    }
resume:
    int i=0;
    if(++i==5)  goto exit;
label1:
    cout << " This is label1" << endl;
    goto resume;
label2:
    cout << " This is label2" << endl;
    goto resume;
exit:
    return 0;
}

$ g++ -g goto.cpp
goto.cpp: In function 'int main()':
goto.cpp:26:14: error: label 'to' used but not defined
         goto to;
              ^~
