@pbdeuchler this has probably different root causes as my and your query stack during panic: s are different.
What version of bitvec are you compiling?

A convenience crate was pulling it in, i've removed the code calling that crate so I can't be 100% sure but diffing from the latest commit (a couple days ago) it looks like:

-[[package]]
-name = "bitvec"
-version = "0.18.5"
-source = "registry+https://github.com/rust-lang/crates.io-index"
-checksum = "98fcd36dda4e17b7d7abc64cb549bf0201f4ab71e00700c798ca7e62ed3761fa"
-dependencies = [
- "funty",
- "radium",
- "wyz",
-]
-

Which is about 3 years old. It was compiling just fine on nightly the other week though.

I submit the ICE from bitvec to another issue: #110682
