I've just run the test suite through ASan with an undumped emacs on macOS.
I got lots of dynamic-stack-buffer-overflow errors when using SAFE_ALLOCA,
which I can't explain; maybe that's indeed an ASan bug because alloca isn't
that widely used.
There's one actual bug: the sockaddr_in in line 3538 of process.c needs to
be sockaddr_storage, otherwise it's too small for IPv6. (And
conv_sockaddr_to_lisp should probably check that the address is of the
expected length and not blindly overwrite the len argument.)
