rust version is nightly-x86_64-pc-windows-msvc unchanged - rustc 1.82.0-nightly

error message is:
error: process didn't exit successfully: target\debug\examples\testk.exe (exit code: 0xc0000374, STATUS_HEAP_CORRUPTION)

debug and release build are the same.

I'm facing the same issue, I cannot get the example to run

I don't have Windows, so unfortunately I can't test it myself, but let's try to work something out:

Which of the examples did you try to run exactly? I only see testk.exe and that seems weird to me. I would expect either lloyd, minibatch, or status_events.

To debug this, can you please try running the same example using cargo miri and send me the output? For example, to run the lloyd example, do:

cargo miri run --example lloyd

I had to simplify the example, otherwise cargo miri took forever to run. This is the lloyd example with the following parameters:

    let (sample_cnt, sample_dims, k, max_iter) = (5, 2, 4, 10);

    = help: this program is using integer-to-pointer casts or (equivalently) `ptr::with_exposed_provenance`, which means that Miri might miss pointer bugs in this program
    = help: see https://doc.rust-lang.org/nightly/std/ptr/fn.with_exposed_provenance.html for more details on that operation
    = help: to ensure that Miri does not miss bugs in your program, use Strict Provenance APIs (https://doc.rust-lang.org/nightly/std/ptr/index.html#strict-provenance, https://crates.io/crates/sptr) instead
    = help: you can then set `MIRIFLAGS=-Zmiri-strict-provenance` to ensure you are not relying on `with_exposed_provenance` semantics

Mhm. Weird, I see the same error in Linux. But it reliably doesn't crash.

Just to be sure, can you please also run:

MIRIFLAGS="-Zmiri-disable-stacked-borrows" cargo miri run --example lloyd

This was a known bug in the crossbeam crate, that is fixed on their master-branch. The fix has not been released yet, so you will have to fix it by pinning crossbeam to master.

Can you try running it again with the following workaround in your Cargo.toml please?

[patch.crates-io]
crossbeam = { git = "https://github.com/crossbeam-rs/crossbeam.git" }
crossbeam-epoch = { git = "https://github.com/crossbeam-rs/crossbeam.git" }
