I tried this code: 5b9d468, and then renamed the top-level directory from rust to rustc.

I expected to see this happen: The compiler can bootstrap itself (possibly giving an error about the change in rustdoc, I forget if that code compiles).

Instead, this happened:

error: internal compiler error: encountered incremental compilation error with item_children(build_helper[daa7])
