this is due to supertag using an old version of lexical-core which is incompatible with new versions of rust, which is fixed upstream in rust-lexical here, but supertag hasn't updated its dependencies and made a new release yet
A easy fix would be to patch its Cargo.lock to use a newer version of lexical-core
hydra failure if anyone is interested
