What are common issues with ThreadSanitizer?

What are some common issues I might encounter when using ThreadSanitizer?

Some common issues include false positives, performance overhead, and difficulty in interpreting reports.

Can you explain what false positives mean in this context?

False positives occur when ThreadSanitizer reports a data race that isn't actually present, leading to confusion.

How can I reduce the performance overhead when using it?

You can reduce overhead by limiting the scope of instrumentation and focusing on specific threads or code sections.

Are there any best practices for interpreting the reports?

Yes, focus on the stack traces, understand the context of the reported races, and correlate them with your code.
