@WaffleLapkin Were you modifying the compiler locally before performing this build? I'm not sure where rustc_query_system::query::plumbing::QueryCacheStore<bool> is coming from, since bool is not a QueryCache.

WaffleLapkin commented 2 years ago

@Aaron1011 no, I only updated the core (it's this PR: https://github.com/rust-lang/rust/pull/91216)
