malloc: 对象 0x00 的 *** 错误:未分配正在释放的指针

我创建了这个小型玩家管理系统。但是每当我搜索或更新玩家的信息时都会收到此错误。另外，我没有进行任何动态内存分配，所以我不确定为什么存在释放指针的问题。

a.out(1599,0x10802e5c0) malloc: *** error for object 0x7fd4d0d000c0: pointer being freed was not allocated
a.out(1599,0x10802e5c0) malloc: *** set a breakpoint in malloc_error_break to debug
Abort trap: 6

Segmentation fault: 11也被打印出来。
