after updating from Rust 1.79 to Rust 1.80(.1) I can’t compile my code in debug mode (–release works), as apparently something in the library seems to be broken. As others on my team can compile the code with their setup it probably comes from something in my setup.
My setup uses
WSL version: 2.2.4.0
Kernel version: 5.15.153.1-2
WSLg version: 1.0.61
MSRDC version: 1.2.5326
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.26091.1-240325-1447.ge-release
Windows version: 10.0.22631.4037
with VS code 1.92.2 and Rust is
stable-x86_64-unknown-linux-gnu (default)
The full backtrace is:
thread '<unnamed>' panicked at library/core/src/panicking.rs:219:5:

thread caused non-unwinding panic. aborting.
Any hints what could’ve gone wrong?
There are only two parts using unsafe code, both using methods from the hashbrown crate, one using
hashbrown::raw::inner::RawTable
impl<T, A> RawTable<T, A>
pub unsafe fn iter(&self) -> RawIter<T>
the other using
hashbrown::raw::inner::Bucket
impl<T> Bucket<T>
pub unsafe fn as_ref<'a>(&self) -> &'a T
Since the problem appears only on my machine, this is a bit strange.
Tried to wait for the next Rust update (problem consists since 1.80.0). dist-upgrade to make sure WSL Ubuntu is up to date. Cargo clear cache to make sure everything is really clean re-build.
Minimal example which fails:
fn main() {
println!("Hello, world!");
}
#[doc = docify::embed!("src/main.rs", example_env)]
pub mod something {}
#[cfg(test)]
mod tests {
#[test]
#[docify::export_content]
fn example_env() {}
}
with Rust 1.82 beta I get
error: proc macro panicked
--> src/main.rs:5:9

5 | #[doc = docify::embed!("src/main.rs", example_env)]
