The Minimal Complete and Verifiable Example for the Rust Issue #100125

Based on Cocoon project.

Prerequisites

cargo install cargo-bisect-rustc

How To Run

./reproduce.sh

Explanation: if grep finds 80-90% in a coverage report (it looks for a 99% or say 84%, which is also good), so it's just looking for '>9' or '>8', then the script returns 0, else it returns error 1.

1 unit-test may fail, but it doesn't impact reproducibility, because it checks the code coverage.
