The linked reproduction repo appears to no longer exist.

malezjaa commented 1 day ago

I'm sorry. I changed the visibility because I thought you had already found the issue. I had already modified the code to not cause a compiler error.

malezjaa commented 1 day ago

Made it public again. https://github.com/malezjaa/game/commit/7fa40a6b810177ea79c6ace036dd615358976ce8 this commit contains old code in src/cursor.rs

cyrgani commented 1 day ago

Thanks for making it public again. Here is a reduced example of the ICE: https://github.com/cyrgani/rustc-ice-version-conflict The issue why the compiler panics is that rapier depends on bevy 0.14, but the game crate depends on bevy 0.15. When importing a type from rapier in game, the ICE occurs.
