Ambiguous member function call to capture this in lambda

Question

I ran into a problem while trying to call a member function inside a lambda for a captured one this. There is a constant and non-constant version of the function and it is intended for the type.

The following code shows an error:

struct TEST
{
  template <typename T>
  void test() {}

  template <typename T>
  void test() const {}

  TEST()
  {
    [this]()
    {
      test<void>();
    }();
  }
};

I was not sure if this behavior was correct and just a problem with the Microsoft compiler, so I tested the code with gcc and clang in the compiler explorer, and they both compiled the code without errors.

Which compiler displays the correct behavior here?

MSVC. this cv-. - cv-. c'tor this ( - ).

- MSVC . -, this, :

void bar()
{
  [this]()
  {
    this->test<void>();
  }();
}
