自己最近在学习反调试，看到了利用TLS进行反调试这一块，于是自己写了一个小程序进行测试，但是发现只有在Debug下才会进入TLS回调函数，Release版本进不去，请问这是为什么？？？？？求大神解决。
程序运行结果如下:
debug版本:
Release版本:
代码:
#include<windows.h>
#pragma comment(linker, "/INCLUDE:__tls_used")
void print_console(char* szMsg)
{
HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
WriteConsoleA(hStdout, szMsg, strlen(szMsg), NULL, NULL);
}
void NTAPI TLS_CALLBACK1(PVOID DllHandle, DWORD Reason, PVOID Reserved)
{
char szMsg[80] = { 0, };
wsprintfA(szMsg, "TLS_CALLBACK1() : DllHandle = %X, Reason = %d\n",
DllHandle, Reason);
print_console(szMsg);
}
void NTAPI TLS_CALLBACK2(PVOID DllHandle, DWORD Reason, PVOID Reserved)
{
char szMsg[80] = { 0, };
wsprintfA(szMsg, "TLS_CALLBACK2() : DllHandle = %X, Reason = %d\n",
DllHandle, Reason);
print_console(szMsg);
}
#pragma data_seg(".CRT$XLX")
PIMAGE_TLS_CALLBACK pTLS_CALLBACKs[] = { TLS_CALLBACK1, TLS_CALLBACK2, 0 };
#pragma data_seg()
DWORD WINAPI ThreadProc(LPVOID lParam)
{
print_console("ThreadProc() start\n");
print_console("ThreadProc() end\n");
return 0;
}
int main()
{
HANDLE hThread = NULL;
print_console("main() start\n");
hThread = CreateThread(NULL, 0, ThreadProc, NULL, 0, NULL);
WaitForSingleObject(hThread, 60 * 1000);
CloseHandle(hThread);
print_console("main() end\n");
return 0;
