C++ C++；导致seg故障的功能错误,c++,c++11,segmentation-fault,C++,C++11,Segmentation Fault,您好，我有这个函数，我正在尝试从中获取值 struct PlayerMoving { int packetType; int netID; float x; float y; int characterState; int plantingTree; float XSpeed; float YSpeed; int punchX; int punchY; int secondnetID; }; 导致分段错误的

您好，我有这个函数，我正在尝试从中获取值

struct PlayerMoving
{
    int packetType;
    int netID;
    float x;
    float y;
    int characterState;
    int plantingTree;
    float XSpeed;
    float YSpeed;
    int punchX;
    int punchY;
    int secondnetID;
};
导致分段错误的原因


PlayerMoving *pMov = unpackPlayerMoving(tankUpdatePacket);
if (pMov->plantingTree == 18) {
   OnPunch(pMov->punchX, pMov->punchY, world, peer, server);
}
else if (pMov->plantingTree == 32) {
    onWrench(world, pMov->punchX, pMov->punchY, peer);
}
else
{
    OnPlace(pMov->punchX, pMov->punchY, pMov->plantingTree, world, peer, server); //here it show segmentation fault
}
delete pMov;
我遇到了一个分割错误，所以我决定用valgrind来看看发生了什么 然后我在SendPacketRaw中看到了分段故障累加器，但我真的不知道为什么会发生这种情况，知道如何解决这个问题吗

这就是瓦尔格林给我的

==38843==  If you believe this happened as a result of a stack
==38843==  overflow in your program's main thread (unlikely but
==38843==  possible), you can try to increase the size of the
==38843==  main thread stack using the --main-stacksize= flag.
==38843==  The main thread stack size used in this run was 8388608.
