[Bug c++/42043] New: object destroyed at wrong time

2009-11-14 Thread miklcct at gmail dot com 
example code:

#include 
using namespace std;
struct test {
test () {
cout << "test::test()" << endl;
}
~test() {
cout << "test::~test()" << endl;
}
};

struct a {
const test &x;
a () : x(test()){
cout << "a::a()" << endl;
}
~a() {
cout << "a::~a()" << endl;
}
};

int main() {
a obj;
}

Expected result:
test::test()
a::a()
test::~test()
a::~a()

Actual result:
test::test()
test::~test()
a::a()
a::~a()

Std sect 12.2 Temporary objects
3 (...) Temporary objects are destroyed as the last step in evaluating the
full-expression that (lexically) contains the point where they were created.
(...)

4 There are two contexts in which temporaries are destroyed at a different
point than the end of the full-expression. (...)

5 The second context is when a reference is bound to a temporary. The temporary
to which the reference is bound or the temporary that is the complete object of
a subobject to which the reference is bound persists for the lifetime of the
reference expect:
 - A temporary bound to a reference member in a constructor's ctor-initializer
persists until the constructor exits.

[Bug c++/78850] Parameter of returned generic lambda allegedly shadows parameter of free function

--- Comment #1 from Michael Tsang  ---
I think the following is related to this, where the parameter of a returned
lambda is mis-interpreted as shadowing a local variable:

[michael@samsung-rv510 ~]$ cat fix.cpp
#include 

using std::cin;
using std::cout;

struct Factorial {
template unsigned long operator()(Function self, unsigned
long n) const {
return n ? n * self(self, n - 1) : 1;
}
};

template auto y(Function f) {
return [f](auto n) {
return f(f, n);
};
}

int main() {
unsigned long n;
cin >> n;
cout << y(Factorial())(n) << '\n';
return 0;
}
[michael@samsung-rv510 ~]$ g++ -Wshadow -std=c++14 fix.cpp -o fix
fix.cpp: In instantiation of 'y(Function):: [with auto:1 = long
unsigned int; Function = Factorial]':
fix.cpp:21:29:   required from here
fix.cpp:13:22: warning: declaration of 'n' shadows a previous local [-Wshadow]
 return [f](auto n) {
  ^
fix.cpp:19:19: note: shadowed declaration is here
 unsigned long n;
