Access outside of object lifetime example
本文总结我所遇到的access outside of object lifetime。
Example: in multi-thread application
参见 Multi-thread-and-observer-pattern 章节。

Example: iterator invalidation
1、iterator invalidate和object lifetime，Access outside of lifetime of object 有关。
2、关于 Iterator invalidation，参见 C++\Library\Standard-library\STL\Containers-library\Common-issue\Iterator-invalidation 章节；
3、Pointer invalidation，参见:
a、stackoverflow What exactly is invalidation of reference/pointer?
Example: realloc and move
dangling pointer and object lifetime and vector<std::string> and，realloc and move
Example: Calling Virtual During Initialization
参见:
1、Classes\Object-lifetime 章节，其中对此进行了详细描述。
2、cppreference virtual function specifier # During construction and destruction
Example: access local object
源自: cppreference Lifetime
int* foo(void) {
int a = 17; // a has automatic storage duration
return &a;
} // lifetime of a ends
int main(void) {
int* p = foo(); // p points to an object past lifetime ("dangling pointer")
int n = *p; // undefined behavior
}
APUE 11.4 Thread Creation
The typeless pointer passed to pthread_create and pthread_exit can be used to pass more than a single value. The pointer can be used to pass the address of a structure containing more complex information. Be careful that the memory used for the structure is still valid when the caller has completed. If the structure was allocated on the caller’s stack, for example, the memory contents might have changed by the time the structure is used. If a thread allocates a structure on its stack and passes a pointer to this structure to pthread_exit, then the stack might be destroyed and its memory reused for something else by the time the caller of pthread_join tries to use it.
