[95th]

If I ran cargo clean and then cargo check again, the error stopped coming. 🤔

[jonas-schievink]

Can you provide the source code needed to reproduce this?

[95th]

The (not a lot of) code is at:
https://github.com/95th/btrs

I myself cant reproduce with the same code now.. I tried cargo clean once and now it doesnt ICE.

[eloraiby]

Have similar issue:

running cargo clean and then cargo build fixes the issue.

[jonas-schievink]

It is unlikely that we will be able to do anything here unless:

• This is reproducible on nightly
• A reliable way to reproduce the issue is found (eg. two commits that cause the issue when built in sequence)

[95th]

Closing as I don't have an MCVE and it doesn't reproduce even with the same code.

[eloraiby]

Wait, this is a bug, being hard to produce doesn't mean it doesn't exist. It should be reopened as it's not solved. Worst case put it to low priority, but definitely not closed.

[95th]

Sure.. I guess if someone else finds an MCVE, they can post here.
