Right. FWIW, non-ancient *BSD's also have asprintf(), and with slightly
safer semantics than glibc: on error, they not only return -1, but also
reset the pointer to NULL. Dmitry V. Levin of ALT Linux tried to push
this semantics change to glibc, but Ulrich rejected it. So it remains
in a patch in ALT Linux and Owl.
It would be nice for cluts to test non-portable functions like that as
well, when they're available, and to point out semantics differences
like this (not as errors, but as properties of the given platform).
