问题描述
过去几天，我一直在努力解决malloc错误，而我在解决方案上的想法已用尽。该项目（在C和SDL2中毁灭性毁灭的创建）在macOS Mojave和Catalina（精确版本为idk）上运行良好，但在我的OS（High Sierra 10.13.6）上崩溃。我们正在使用clang进行编译。
错误：
doom(76767,0x7fff9d07c380) malloc: *** error for object 0x7fe50486b800: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
[1] 76767 abort ./doom
我尝试确定发生错误的确切行，即使我摆脱了对free()的所有调用（出于测试目的），似乎在整个程序中都可以访问已释放的变量。那就是我开始变得绝望的地方。
这样的事情怎么发生？我在另一篇SO文章中读到，问题可能不是无效的免费，而是错误的malloc。你们将如何寻求解决方案？另外，为什么只在10.13而不是莫哈韦沙漠和卡塔琳娜州出现此问题？
由于没有一行引起问题的具体代码，因此很难张贴代码示例。如果您想看一下代码，我很乐意向您发送github链接。
