Why would the size be `LLDB_INVALID_ADDRESS`? Did you mean to check that the range base isn't `LLDB_INVALID_ADDRESS`? 

Is this the condition you want?

```
(region.GetRange().GetRangeBase() == 0 || region.GetRange().GetRangeBase() == LLDB_INVALID_ADDRESS) && region.GetRange().GetByteSize() == 0) 
```
