internal compiler error: src/librustc_middle/ty/query/mod.rs:105:1: tcx.dep_kind(crate0) unsupported by its crate

[jyn514]

Reproduction steps

I have no idea. Originally this happened from rebasing bfed930 over daecab3, but I had lots of strange changes to x.py in the meantime, so I doubt that alone will replicate the build state. However the panic happens consistently, so I can upload a zip of the build directory if someone knows a place to host 10 GB of binary artifacts.

Meta

This is using a stage1 build of rustc. I think the cache may possibly not have been invalidated?

query stack during panic:
#0 [dep_kind] fetching what a dependency looks like

#2 [analysis] running analysis passes on this crate
end of query stack

[jyn514]

Also this has the changes to x.py that I made in #73964, so maybe I introduced a bug myself?

[jyn514]

However the panic happens consistently, so I can upload a zip of the build directory if someone knows a place to host 10 GB of binary artifacts.

This is no longer the case, I've since lost the state of the build directory.

[wesleywiser]

@jyn514 confirmed they haven't experienced this since reporting the issue 4 months ago. It seems likely the root cause was the changes to rustbuild they were working on. I've looked through the issue tracker and can't find any similar issues reported other than this so we're going to close for now.

If this happens again, feel free to re-open.
