我看到了 gdb 在核心转储后转储所有线程的回溯的这一漂亮的衬线。所以我尝试了一个快速：
int main() {int* x = new int[5]; for(int i = 0; true; ++i) x[i] = i; }
获取核心转储，然后运行：
gdb --batch --quiet -ex "thread apply all bt full" -ex "quit" a.out core.box-name.a.out.27459.8515.11
我得到输出：
[New LWP 27459]

i = 33788
x = 0x1a460010
我看到一个很好的回溯，但我想知道我还看到的两个警告是关于什么的？
