Looks like this upstream bug in tarpaulin: xd009642/tarpaulin#1307 (if so, it is fixed already in a dev branch of tarpaulin, we just need to wait.)

Actually, the release is already out. To fix this if you are affected, just upgrade tarpaulin with cargo install cargo-tarpaulin. It is fixed with tarpaulin 0.27.0 (at least).
