Failed to get current dir

Error message

Failed to get current dir

What it means

`run_rustc` reads the current working directory to record it with the captured rustc args; this panic fires if `std::env::current_dir` fails, which happens when the process's working directory has been deleted or is otherwise inaccessible.

Solutions

1. Run the command from a directory that still exists and is accessible; recreate or cd into a valid working directory if it was deleted.
