| |
| <p>Once you think you have found an error in your program, you might want to |
| find out for certain whether correcting the apparent error would lead to |
| correct results in the rest of the run. You can find the answer by |
| experiment, using the <small>GDB</small> features for altering execution of the |
| program. |
| </p> |
| <p>For example, you can store new values into variables or memory |
| locations, give your program a signal, restart it at a different |
| address, or even return prematurely from a function. |
