The DH_set0_key() in src/node_crypto.cc is a backwards compatibility shim for the function of the same name in openssl 1.1.0, where it returns int.

Ah I see that now, thanks for clarifying!

Is there a reason for not declaring the return type for the function pointer? I've added a commit with what I mean.

Since you're threading through the return value, you might as well CHECK_EQ(1, set_field(dh->dh, num));.

Should this be backported to v8.x-staging? If yes please follow the guide and raise a backport PR, if no let me know or add the dont-land-on label.
