其實是在說下面這段程式…

1 #include <list>
2 #include <iostream>
3 using namespace std;
4 int main()
5 {
6 list<int> a;
7 a.pop_front();
8 a.pop_front();
9 a.pop_front();
10 a.pop_front();
11 a.pop_front();
12 a.pop_front();
13 a.pop_front();
14 a.pop_front();
15 cout <<a.size()<<endl;
16 return 0;
17 }

在某台跑的結果是

alex@xxxxxx [17:33] ~> ./a.out
a.out in free(): error: malloc() has never been called
Abort

結果另外一台是

yhsung@oooo [5:20pm] ~> ./a.out
a.out in free(): warning: malloc() has never been called
a.out in free(): warning: malloc() has never been called
a.out in free(): warning: malloc() has never been called
a.out in free(): warning: malloc() has never been called
a.out in free(): warning: malloc() has never been called
a.out in free(): warning: malloc() has never been called
a.out in free(): warning: malloc() has never been called
a.out in free(): warning: malloc() has never been called
0

另外試很多台, 看起來應該是要crash吧? @_@
