We had a stack use-after-return last month that people had to debug by hand. that would have been caught by ASan with stack-use-after-return. So

What type of failures do you mean? Does the symbol mismatch break assumptions in the ASan runtime? It's easy to imagine, for example, ASan missing use-after-free bugs because the call to free() is

For the same reason we use shared runtime on OSX. We intercept libc calls by declaring a function with the same name in the sanitizer runtime library. Glibc loader puts main executable early in the symbol lookup order, which lets us interpose symbols from shared libraries with symbols from statically linked sanitizer runtime. Android (and AFAIK most other platforms) does not allow that, which is
