In the PR where I enabled the hardening, there's an ASan error (consistent and unique to the PR - cidb).
It occurs in unique_ptr code:
because
__in_boundsreads array cookie directly from memory which is marked as poisoned by the sanitizer.That should be read via
__asan_load_cxx_array_cookie(code) instead as it checks if the memory is marked askAsanArrayCookieMagicand if so, just returns the cookie.
