Incremental ICE: could not find ICH for FileMap

[ishitatsuyuki]

The compiler is a little bit old, but I didn't see any open discussion about this.

rustc 1.19.0-dev (1d468400f 2017-05-11)
binary: rustc
commit-hash: 1d468400f5bf205a92eabdededc17e0a2789d651
commit-date: 2017-05-11
host: x86_64-unknown-linux-gnu
release: 1.19.0-dev
LLVM version: 4.0

I suspect this becomes broken when I use workspace? I was testing #41369.

error: internal compiler error: src/librustc_incremental/calculate_svh/mod.rs:89: Could not find ICH for FileMap(DefId { krate: CrateNum(0), node: DefIndex(0) => cargo/210d1058e686a5256f66a17dfa7d9257 }, "src/cargo/util/machine_message.rs")

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

This should be fixed by #41873. Would you mind giving it another try with the latest nightly?

[ishitatsuyuki]

I have cleaned the directory already, so feel free to close this issue as duplicate.

Thanks, @ishitatsuyuki!
