数和一个无符号数进行比较时,有符号数会先转换成无符号数,然后再进行比较。 重点在这 那么,假设,我们doublefree同一个堆,那么在tcachebin里就会构成循环链表,此时count=2,然后...出libc中的指针。 形成双向链表,那么我们create后,写入一个新地址,那么新地址就会链接到tcachebin链表的后面,我们看看 那么,我们再mal...

双重释放(double free)是什么? 在C++中,双重释放会导致什么问题? free()是C++编程语言中的一个函数,用于释放动态分配的内存空间。在C++的tcache2中检测到双重释放是指在使用tcache2内存管理机制时,检测到同一块内存被重复释放的情况。 tcache2是C++标准库中的一种内存管理机制,用于提高内存分配和释放的效率。它...
