Is this safe?

I don’t want to be bothered by VMProtect when I am just debugging my code so I put a res = 0 surrounded by
#ifdef _DEBUG / #endif preprocessor conditions. It it dangerous to have this code in the exe in the wild?
I have put it inside the protected code area using a marker.

char serial = read_serial((char)“c:\serial.txt”);
int res = VMProtectSetSerialNumber(serial);
delete serial;

VMProtectBegin(“Create”);

#ifdef _DEBUG
res = 0;
#endif

if (res)

{

Thanks in advance
