--- Comment #16 from Antony Polukhin <antoshkka at gmail dot com> ---
Can we increase the priority of this issue to P1 or P2? It affects the very
basics of the C++.

BTW, I've minimized example. It aborts on every version of GCC with -std=c++11,
passes on Clang:


int constructed = 0;

class lock_guard_ext{
public:
    lock_guard_ext() { ++constructed; }
    ~lock_guard_ext() { --constructed; }
};

struct Access {
    lock_guard_ext lock;
    int value;
};

int t() {
    throw 0;
}

Access foo1() {
    return { {}, t() };
}

int main () {
    try {
        foo1();
    } catch (int) {}
    if (constructed != 0)
        __builtin_abort();
}
