Buffer Overflow

Hi Secprogrammers

Here my stupid question.
If I compile my final build with the checkboxes:
- Range checking   ( Checks that array and string subscripts are within 
bounds. Corresponds to {$R}) .
- I/O checking    (Checks for I/O errors after every I/O call. 
Corresponds to {$I}.)
- Overflow checking   ( Checks overflow for integer operations. 
Corresponds to {$Q}.)

checked . Could this minimize the possibility of occurrences of buffer 
overflows or other similar security holes?


Thanks
