Compiler Warning (level 1) C4420
'operator' : operator not available, using 'operator' instead; run-time checking may be compromised
This warning is generated when you use the /RTCv (vector new/delete checking) and when no vector form is found. In this case, the non-vector form is used.
In order for /RTCv to work correctly, the compiler should always call the vector form of new/delete if the vector syntax was used.
