Issue: thread 'rustc' panicked at 'called `Option::unwrap()` on a `None` value', compiler/rustc_metadata/src/rmeta/def_path_hash_map.rs:18:85
Labels: I-ICE,T-compiler,A-incr-comp,C-bug

Note:
This may have something to do with incremental compilation. I had just moved a struct to another file, and some code which should not have passed cargo check because it referenced that struct by the old path still compiled. Only after I saved the file referencing the invalid path with the fixed path did the panic occur.
