class ClassA {
public:
virtual ~ClassA() = default;
virtual auto Foo(int num) const -> int abstract;
};
class ClassB : public ClassA {
public:
auto Foo(int num) const -> int override:
};
====>> changing signature via "Change Signature" -> Foo(..., bool on) // adding another parameter
class ClassA {
public:
virtual ~ClassA() = default;
virtual auto Foo(int num, bool on) const -> int abstract;
};
class ClassB : public ClassA {
public:
auto Foo(int num, bool on) const -> int abstract override // <<----- abstract AND override! only override is correct
};
I noticed this behavior since ages.

Apologies for the slow reply. I am seeing the same problem here, thank you for the very clear example:
case=148821
This might be a strange question, but what language are you compiling this as? Actual C++ or C++/CLI, or something else? This compile quite happily for me as C++, but "abstract" isn't a C++ keyword.
For the bug, if you trigger Change Signature in the child class, "ClassB", do you still see the problem? I don't see the bug when doing this, only when triggering Change Signature in the base class. |

We use MSVC (Microsoft Visual C++ compiler) v142. The language we use is ISO c++ 17 Standard C++ and sometimes also C++/CLI, but there is no difference what the behavior concerns.
"abstract" seems to be a Microsoft specific keyword.
If I replace abstract by = 0, it works perfectly, on base or derived class.
If I trigger Change Signature on the child class member the "abstract" on the base member will disappear, the rest of the signatures is correct. |

| Thank you for the update, yes, it does indeed seem that abstract is a Microsoft specific keyword, but the meaning of the code is clear, which is what matters. |
