soundcraft/crates/vst3-host/tests/module_exit_live_instance.rs

//! A module with a plugin instance still alive at process exit keeps running: its module exit
//! would pull the module out from under that instance (`harness = false`, see `module_exit.rs`).
//! The fixture aborts the process if its module exit runs while any of its objects are alive.
