当输入超出了预分配的空间大小,就会覆盖该空间之后的一段存储区域,这就叫Heap Corruption。这通常也被用作黑客攻击的一种手段,因为如果在该空间之后的那段存储区域如果是比较重要的数据,就可以利用Heap Corruption来把这些数据修改掉了,后果当然可想而知了。 在VC里面,用release模式编译运行程序的时候,堆分配(Heap a...

Other scenarios may also trigger SIGSEGV crashes, which include stack overflow memory access, heap overflow memory access, global wild pointer access, execution on an invalid address, and invalid parameter invocation. The SIGSEGV crash is associated to the stack allocation and recovery of the ...
