windbg分析死鎖問題

**如下：

#include #include #include using namespace std;

critical_section cs_db1;
critical_section cs_db2;
dword winapi threadproc(lpvoid lpparam)
void main()
deletecriticalsection(&cs_db1);
deletecriticalsection(&cs_db2);
}

輸入命令：~*kb，發現兩個地方都有rtlentercriticalsection+0x150

通過命令!cs將臨界區轉儲存出來

觀察owningthread，發現第乙個臨界區被執行緒1c30持有，第二個臨界區被執行緒1864持有，所以產出死鎖。
