## Sanitizers
Address sanitizer.
**Address sanitizer**.
We run functional tests under ASan on per-commit basis.
Valgrind (Memcheck).
**Valgrind (Memcheck)**.
We run functional tests under Valgrind overnight. It takes multiple hours. Currently there is one known false positive in `re2` library, see [this article](https://research.swtch.com/sparse).
Thread sanitizer.
**Thread sanitizer**.
We run functional tests under TSan. ClickHouse must pass all tests. Run under TSan is not automated and performed only occasionally.
Memory sanitizer.
**Memory sanitizer**.
Currently we still don't use MSan.
Undefined behaviour sanitizer.
**Undefined behaviour sanitizer.**
We still don't use UBSan. The only thing to fix is unaligned placement of structs in Arena during aggregation. This is totally fine, we only have to force alignment under UBSan.
Debug allocator.
**Debug allocator.**
You can enable debug version of `tcmalloc` with `DEBUG_TCMALLOC` CMake option. We run tests with debug allocator on per-commit basis.
You will find some additional details in `dbms/tests/instructions/sanitizers.txt`.
