@estebank what does |
|
@PaulGrandperrin we would like to have a minimal reproducible example of the problem. Ideally it would be something that we can eventually put in the test suite to catch regressions, but if you could push out a repo that reproduces the problem, that would be enough for us to identify what is triggering the problem. The backtrace is very useful, but being able to test and verify potential solutions is necessary to be able to land any PR fixing this. |

Found while investigating rust-lang#82933 - all LocalDefIds are expected to have HirIds, there's no point in pretending otherwise.

I just ran into this after simply having a typo in an #![allow0(clippy::use_self)]unfortunately the entire project is too large and closed-source to be a repro, but I was confused how a simple typo triggered this. I guess it was just bad luck :( backtrace

@extrawurst Are you able to get a more recent version of nightly? |
|
@PaulGrandperrin Can you still reproduce this? If you can, could you provide instructions? Someone else may come along and create an MCVE. |
|
Fixed and testcase was added in #84168, so can somebody please close this? :) |
|
@hellow554 that PR links to #84149, not here. Did you mean a different PR? |
|
@jyn514 I'm very confused myself, so bear with me. I was cleaning up my open issues, where I was stumbling upon #74318, which has a different ICE than before. Because of that I closed that issue and look up similar ones (with the same error message) and landed here. Does this make sense? |
I got this bug deep in the middle of trying things (abstracting some code of
sqlx'sExecutortrait, similarly to https://github.com/eaze/tide-sqlx/blob/latest/src/lib.rs).My codebase at this time is a big work-in-progress mess so I won't post it now, but I saved it.
The bug is reproducible, and I can give you more information if needed!
