14.3.2 Exception handling:Constructors and destructors:2 (https://eel.is/c++draft/except.ctor#2)
says
"If an exception is thrown during the destruction of temporaries or local variables for a return statement ([stmt.return]), the destructor for the returned object (if any) is also invoked"

And it contains example (https://eel.is/c++draft/except.ctor#example-1) with description
"...the local variable y is destroyed, causing stack unwinding, resulting in the destruction of the returned object, ..."

Trying to recreate this example with following code

#include <iostream>
using namespace std;

struct S{
  int i = 123;
  S(int i) :i(i) {cout<<"S("<<i<<")"<<endl;}
  ~S() {cout<<"~S("<<i<<")"<<endl;}
};

struct T {
  T() {cout<<"T()"<<endl;}
  ~T() noexcept(false) {
    cout<<"~T()"<<endl;
    throw 0;
  }
};

S foo() {
  try {
    T t;
    return {3};
  } catch (...){}
  return {4};
}

int main() {
  foo();
}

Output doesn't have S{3}'s (returned object) destruction line:
T()
S(3)
~T()
S(4)
~S(4)

while should be
T()
S(3)
~T()
~S(3) <-----!
S(4)
~S(4)
