--- Comment #3 from kaijun <kaijun at seed dot net.tw> ---
In Arch Linux & use [gcc 4.9.2]

The same problem happened again.

//This bug could be reproduced as following code on gcc 4.9.2
// g++ -Werror -Wall -O2 t.cpp -o t
class B {
public:
    virtual ~B(){};
};
class A {
public:
    B   m1[1];
    B   m2[1];
    B   m3[1];

    A(){};
};
int main() {
        A v;
        return 0;
}
