Hey, so I was compiling a project and I found a bug that was directed to here.

You can reproduce this error by using my project as explained below. I am happy to answer other questions, but I am not sure I even know where to look. I'll try to get a smaller example.

git clone -b rustc_bug https://github.com/SIMPLE-BuildingSimulation/heat.git
cd heat
cargo check --features parallel

Code

/* The problem is in line 206 of file src/model.rs */

// ...
) -> Result<(), String> {

    #[cfg(not(feature = "parallel"))]
    let surface_iter = surfaces.iter().zip(alloc.iter_mut());
    #[cfg(feature = "parallel")]
    let surface_iter = surfaces.into_par_iter().zip(alloc.par_iter_mut()); // <-- When the iterator is produced like this

    

    let results = surface_iter.map(
        |d: (&ThermalSurfaceData<T>, &mut SurfaceMemory)| -> Result<(), String> { // <-- (that iterator is used for this).
// ...
