ThreadSanitizer is a tool that detects data races. It consists of a
compiler instrumentation module and a run-time library.
Typical slowdown introduced by ThreadSanitizer is about 5x-15x.
Typical memory overhead introduced by ThreadSanitizer is about 5x-10x.
UBSan is integrated with gcc and clang and can be enabled via a meson
option: -Db_sanitize=thread.
