When I was doing a lot of C++ gamedev, we were definitely doing a lot of stuff that would trip up static analysis, e.g. X-macros. We would still use refactoring tools even though they would often miss stuff. You just rely on a combination of refactoring tool / search and replace / the compiler. We would also debug our code in release mode with symbols. You get used to a debugging environment where you don't trust anything you're seeing in variables, etc. too.
