Yes. The OMPT startup code in libomp assumes libarcher.so to be the last element of the OMP_TOOL_LIBARARIES var. So, as long as you don't load a different OMPT tool while executing an application built with TSan, you will have Archer loaded. To verify, you can export `ARCHER_OPTIONS=verbose=1`. If you have doubts or if loading Archer fails for you, you can export `OMP_TOOL_VERBOSE_INIT=stdout` to get detailed information about OMPT initialization including dlerror output.
