ICE: assertion failed: self.stashed_diagnostics.is_empty() #12364
Closed
Description
Summary
We run clippy checks as part of our CI workflow in the esp-hal project. We have been using the nightly release channel for various reasons, and this has largely not been a problem over the last couple of years.
As of yesterday (2024-02-26) this ICE has reared its head. I had expected this to be resolved with a new nightly release, as has usually been the case in the rare cases we encounter problems like this, however we are still experiencing this ICE.
The most recent workflow run (as of time of writing) can be seen failing here:
https://github.com/esp-rs/esp-hal/actions/runs/8066109592/job/22033416529
I apologize, I am unable to provide a minimal verifiable example at this time; if my schedule clears up this week perhaps I can look into it, but can't make any promises.
