c++ - Usage of "this" in destructor

Question

Is it valid to call some function in destructor with this argument? Function does not store pointer, but assume full-functional object.

Answer 1

this is still valid in the destructor.

However, you need bear in mind that virtual functions no longer work properly as you might expect once the object is being destroyed; see e.g. Never Call Virtual Functions during Construction or Destruction. Essentially, the dynamic type of the object is modified as each destructor completes.
