--- Comment #2 from Sergey Matveev <earthdok at google dot com> --- This is also discussed in the email thread following the clang commit: https://www.mail-archive.com/cfe-commits@cs.uiuc.edu/msg106622.html You could say that by passing -fsanitize=address at link time, we explicitly tell clang to link in the sanitizer runtime. So -nodefaultlibs shouldn't negate -fsanitize=address much as it wouldn't negate -lc. I think this was the logic behind the final decision. While -l:libasan.a helps, it must be applied to non-shared objects only, which is more awkward than just adding -fsanitize=address.
