--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
And looking at
https://code.google.com/p/address-sanitizer/wiki/ExampleUseAfterReturn - it
seems as if the options is called -fsanitize=use-after-return with Clang.
Having different names for the same feature is a bit unfortunate, too.
Especially as GCC -fsanitize= links to Wiki pages which are Clang centric.
