The ICE message is somewhat confusing and overly specific - the issue is that there's no MIR available. This should make debugging these ICEs easier since the error tells you what's actually wrong, not what it was trying to do when it failed. cc rust-lang#80952 (comment)

Does anyone know if this could happen normally (without messing with bootstrap)? The fact that it showed up without changes to rustc makes me think you could replicate it just by running cargo check on one crate and cargo build on another. |

Got it, thanks. This seems worth turning into a proper error then, the same way "multiple matching crates is an error". Doesn't have to be here, though. It would be nice to print the file the crate metadata came from, the way "multiple matching crates" does. Not sure if you can do that outside rustc_metadata. |
