What are the points to consider while using Stepping Backwards feature in Debugging?

The following points needs to be considered while using Stepping Backwards, or Move to Line feature:

This only changes the program counter. Any variable changes/etc are not affected or reverted.
In case of highly optimized code, there might be multiple sequence points per source line. So doing this for highly optimized code might not work correctly.
It works ok within a function. It is not recommended to use it, for example, to set the PC outside of a function, because the context/stack frame is not set up.

Tip: You can use the Move to Line feature frequently to advance the program execution. For example, to bypass some long sequences, or to get out of an endless loop.
