While reproducing the build failure in #55163, i funnily enough got a little further than Travis-CI, running ran into this compiler error:

error: internal compiler error: librustc/ty/context.rs:275: node unknown node (id=651506) with HirId::owner DefId(0/0:0 ~ core[3723]) cannot be placed in TypeckTables with local_id_root DefId(0/0:1812 ~ core[3723]::panicking[0]::panic_fmt[0])

thread 'main' panicked at 'Box<Any>', librustc_errors/lib.rs:599:9
note: Run with `RUST_BACKTRACE=1` for a backtrace.

I've no idea how to continue from here and what might be relevant, so here's the complete log with backtraces enabled:

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.31.0-dev running on x86_64-unknown-linux-gnu
