Hello, I am trying to build and run a thread sanitized mysqld binary. In the CMake configuration, I see the WITH_ASAN option, however, I do not see an option to build mysqld with the thread sanitizer.
After making some custom configurations, I was able to build a mysqld binary with the thread sanitizer (by linking static thread sanitizer), however, when trying to run it, I got the following error: "ThreadSanitizer: sync allocator overflow (65536*1024). Dying." This error seems to be coming from the tsan library and seems this error is caused by too many synchronizations [1]. Reducing the number of threads also didn't help me with this error. So my questions to you experts: 1. Do you run mysqld with the thread sanitizer ? 2. If yes, could you please share the details. (e.g., CMake configurations, compiler/linker flags etc.) 3. If not, any suggestions to overcome the above error ? [1] https://groups.google.com/g/thread-sanitizer/c/AX5twD_IPP4 Thank you.
