            Bug ID: 31386
           Summary: All temporaries aren't destroyed in InitListExpr
                    filler
           Product: clang
           Version: 3.9
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11

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.
