All the time.
Bail is routinely set at $1m or more for high-profile crimes. If the government needs that kind of guarantee, they shouldn't be releasing the defendant at all.
Excessive fines... does confiscation of property count? You possess an oz of marijuana and your house can be forfeit.
Cruel and unusual punishment... absurd mandatory sentencing enhancements for possession of a firearm during the commission of a crime, even if it's not used.
