Indeed gcc's thread sanitizer might report false positives if code which was not compiled with gcc's -fsanitize=thread option performs atomic variable access. Such access cannot be intercepted by the thread sanitizer and could lead to those false positives . Nevertheless, ...
gcc从4.8版本起,集成了Address Sanitizer工具,可以用来检查数据竞争的问题(编译时指定“-fsanitize=thread -fPIE -pie”)。以上面程序为例: gcc -fsanitize=thread -fPIE -pie -g -o a a.c -lpthread 执行a程序: [root@localhost nan]# ./a === WARNING: ThreadSanitizer: data race (pid=14545) Write...

When building facebook/folly with GCC-9.3.0 under TSan, the following data race is intermittently reported, however I believe this is a false positive as the write has a memory barrier (folly::Baton<> started) between it and the read: Te...
