Running latest Oyente on contract:
https://etherscan.io/address/0xae98b0e0c112b6d85ba32ff521b051f3fb2bafab#code
extracted binary via etherscan API:
0xae98b0e0c112b6d85ba32ff521b051f3fb2bafab.txt

Many other contracts pass this way.

cmd
docker start oyente_cont && docker exec -i oyente_cont python /oyente/oyente/oyente.py --compilation-error --depthlimit 4 --looplimit 100 -s 0xae98b0e0c112b6d85ba32ff521b051f3fb2bafab.txt -b
