Could you share the code to reproduce the ICE?

[Noratrieb]

Also, could you verify that this issue is still present on the latest nightly version?

rustup toolchain install nightly
cargo +nightly build

[nlopes]

@Nilstrieb I was about to submit an issue with (I think) this very same issue.

In the hopes that this helps (and yes, it is still present in the latest nightly version) although the compiler seems to point to a slightly different line.
If this is not related please let me know and I can open a different issue (and apologies in advance).

Unfortunately I wasn't successful replicating it with "simple" code. This just started popping up in one of my codebases.

[nlopes]

Ok, here's a minimal reproducible https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=b43429b7dd2b8bced5616a9178a32b36

It requires an external crate: proptest.

cargo +stable test or cargo +beta test runs just fine. cargo +nightly test panics.

[bluelhf]

Also running into this with Warp — I'm not skilled enough to construct an MVCE, though. I wonder if the proptest example could be minified further into self-contained code?
