Aborted (core dumped) 这次终于崩溃了,但显示确实内存越界问题,并且排序后第一个元素是0,这不是我们vector中的元素啊,看来肯定是出问题了 反复尝试几次又找到一个测试用例: std::vector<int>values{3,5,4,4,5,1,4,5,1,4,5,1,4,5,1,4,5,1,4,5,1,4,5,1,4,5,1,4,5,1,4,5,1,4,5,1...

eric@ubuntu:~/work/cmake_work/study/mutex/mutex01/build$ ./testprj double free or corruption (fasttop) Aborted (core dumped) 在linux下,产生Aborted (core dumped)错误。 总之,没有正常输出都是由于多线程同时写入std::vector引起的数据竞争问题。 代码上传至: https://github.com/eric2003/ModernCMake...
double free or corruption You could be trying to free memory after it has already been freed. Or it could be that you're trying to use unallocated memory (eg trying to access past last allocated). Are you using c-style null-terminated strings? Also remember that array access starts at ...
When debugging: before the push_back the contents of origPolys seems correct, and after the push_back the origPolys vector remains unchanged, which isn't the intended behavior, but still not memory corruption. But when I step into the push_back method, this points to nice, well formatted ...
当与cv-未限定的浮点类型(float,double,long double和 cv-未限定的扩展浮点类型(自 C++23 起))之一实例化时,std::atomic提供适用于浮点类型的额外原子操作,如fetch_add和fetch_sub。 此外,生成的std::atomic特化具有标准布局和平凡的析构函数。 即使结果在浮点类型中不可表示,也不会有操作导致未定义的行为。有...
