Internal compiler error when running cargo tarpaulin

[andy128k]

I've got this message when tried to run cargo tarpaulin for my project.

cargo tarpaulin never worked on this project, but rustc's internal error is something new.

$ cargo tarpaulin

Based on the ICE message and the fact that cargo tarpaulin never worked on this project, I am going to guess this is a duplicate of #49362. If you are able to reproduce the crash with a smaller code sample and it is not like what is reported in that bug, please let us know. Thanks!
