Test case
The file:
#include <cstdio>
class Foo {
static int counter;
public:
int objectID;
Foo() { objectID = counter++; }
Foo(const Foo&) { objectID = counter++; }
~Foo() { printf("~Foo() : %d\n", objectID); }
};
int Foo::counter = 0;
struct Bar {
Bar(Foo f = Foo()) {}
};
int main(void) {
Bar b[13] = { Foo(), Foo() };
return 0;
}
compiled with Clang has as output:
$ clang++ test.cpp && ./a.out
~Foo() : 12
~Foo() : 1
~Foo() : 0
which shows that only the last temporary used in the creation of b is
destroyed.</pre>
