Are there C ++ tools that detect the misuse of static_cast, dynamic_cast and reinterpret_cast?

Question

The answers to the following question describe the recommended use static_cast, dynamic_castand reinterpret_castin C ++:

When do you need to use static_cast, dynamic_cast, const_cast and reinterpret_cast?

Do you know any tools that can be used to detect abuse of these types of casts? Can a static analysis tool like PC-Lint or Coverity Static Analysis?

A particular case that raised this question was improper use static_castto lower the pointer, which the compiler does not warn about. I would like to detect this case with a tool and not assume that the developers will never make this mistake.

Answer 1

Given that there is no reliable way to indicate which pointer points to compilation time, this is a rather difficult task that can be caught at compile time.

The easiest way is to make catch at run time using the safe_cast macro, which compiles into dynamic_cast using assert in debug and static_cast in version.
