In setup_cfg() in src/test/test_voting_flags.c a memset is used to write DIGEST256_LEN (32) bytes into signed_descriptor_digest of length DIGEST_LEN (20).

I see 12 bytes of the previously-filled identity_digest being overwritten.

PR to follow.

Looks good to me. Bug not in any released Tor, so no changes/ file is required. Merging!
