Compiler Warning (level 4) C4208

nonstandard extension used : delete [exp] - exp evaluated but ignored

With Microsoft extensions (/Ze), you can delete an array using a value within brackets with the delete operator. The value is ignored.

// C4208.cpp  
// compile with: /W4  
int main()  
{  
   int * MyArray = new int[18];  
   delete [18] MyArray;      // C4208  
   MyArray = new int[18];  
   delete [] MyArray;        // ok  
}  

Such values are invalid under ANSI compatibility (/Za).
