I don't have a strong opinion on this and would prefer someone else to chime in. That said, if we don't hear from someone else by early next week, please go ahead and push. Just one (naive) question: Are there instances where -fsanitize=undefined may be available/working where -fsanitize=address,undefined may be not? If so, perhaps provide both invocations as in <code>-fsanitize=undefined</code> or <code>-fsanitize=address,un... ? Your call; just a thought.
