The flat_sqlite_rs failure is a duplicate of #142424, which is a nondeterministic compile error due to proc macro abuse.

How does one exclude a crate from crater runs?

How does one exclude a crate from crater runs?

Send a PR against crater to exclude it with a brief justification, e.g. rust-lang/crater#778.

[theemathas]

The wsdom-javascript failure is from #141352 (comment). The crate has been fixed in wishawa/wsdom#1, although a new version has not yet been published.
