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 ?

Thank you.
