Since variable within different scope may have same name, I want to use the address of the variable to check if they are same. For example, when the process first stop, I got a variable "a" at address 0x123. While on the next stop, I got a variable "a" at address 0x456, so I know these two "a" are different variables.

My question to you: why are you trying to remove some variables? Are you trying to show all variables for all frames at the same time? If not, you shouldn't be removing any variables. So my question is why are you trying to remove anything?

This isn't going to help you unique anything I would avoid using it.
