Description

I don't know for sure if this a bug or an unexpected intentional decision.

It looks like, based on some experimentation and recent ICE reports on stable such as https://github.com/rust-lang/rust/issues/132240, that the stable compiler does not write and mention ICE files. I don't want that behavior, because some fraction of the time people try to be helpful and abbreviate the compiler's output, and instead omit all the important information.

Research direction

Start by reproducing the behavior on a stable compiler and compare the output with the ICE report linked in issue #132240. Determine whether stable should write and mention ICE files; done means the intended behavior is confirmed and stable compiler output reliably preserves that information.
