对象创建引起的 C++ 奇怪的分段错误

I have a strange problem by initiating a class object. The problem is as strange as well not easily reproducible. However I will try to give an indicating example. I have inheritance classes.

class BarClass {
public:
   BarClass() {
      ...
   }
   BarClass(int i, int j) {
      ...
   }
   void doSomething() { ... }
};
class FooClass : public BarClass {
public:
   FooClass() {
   }
   FooClass(int i, int j) : BarClass(i,j) {
      ...
   }
};

有时如果我用以下方式启动对象，我会通过初始化得到分段错误错误.

FooClass foo1;
foo1.doSomething();
FooClass foo2(10, 20);
foo2.doSomething();

FooClass *foo1= new FooClass();
foo1->doSomething();
FooClass foo2(10, 20);
foo2.doSomething();

FooClass foo1();
foo1.doSomething();
FooClass foo2(10, 20);
foo2.doSomething();

FooClass foo1();
