The lifetime of an object has ended but that object is being
|
|
|
|
|
accessed. For example, the address of a variable holding a C++ object
|
|
|
|
|
is accessed after the variable has gone out of scope:
|
|
|
|
|
|
|
|
|
|
```cpp
|
|
|
|
|
void foo() {
|
|
|
|
|
X* p;
|
|
|
|
|
{ // new scope
|
|
|
|
|
X x = X();
|
|
|
|
|
p = &x;
|
|
|
|
|
} // x has gone out of scope
|
|
|
|
|
p->method(); // ERROR: you should not access *p after x has gone out of scope
|
|
|
|
|
}
|
|
|
|
|
```
