ICE running cargo test

[rib]

Unfortunately I don't have any code I can share to reproduce this currently, and haven't reproduced this since following the suggestion to run cargo clean -p ark_module_store, but perhaps the backtrace will be helpful in diagnosing the cause of the compiler panic.

I was running cargo like:

CARGO_TARGET_DIR=target-windows cargo test -p  ark-module-host-world

[rib]

Possibly a duplicate of #112408 ?

[Noratrieb]

This was probably fixed in #111952. Are you able to reproduce this on beta, which contains the fix?

[rib]

Thanks, I haven't reproduced this since I first hit this but a colleague was hitting something similar repeatedly so I'll ask them to give that a try.

[repi]

@rib don't think we've run into this on later Rust versions, so can probably assumed it gotten fixed and close it?

[rib]

Haven't hit these for a while now, so yeah, sounds reasonable to close.
