There's a patch against 8.4 here:
https://ftp.openbsd.org/pub/OpenBSD/patches/6.8/common/015_sshagent.patch.sig
It has the first of the two changes in your diff. The second is
harmless but unnecessary as it's on the exit path from the function
and there can't be a following call to free.

usually comes from bad judgement.
