Build hang with latest Rust nightly

[MoonKraken]

At some point in the past two weeks it seems like the cargo-leptos build now hangs for me when using nightly. This issue occurs in my CI/CD pipeline with rustlang/rust:nightly@sha256:f243b22fa030754b1e2856b53b9173a1015db0f47c9ae51499fb0348b82ad2b0, and I also reproduced it locally on my mac today with cargo 1.91.0-nightly (840b83a10 2025-07-30). Looking in my build history, it started happening with rustlang/rust:nightly@sha256:483c3564f8ffc7d978fabae5f20b5ad5f6016af607fb7f73170214d4d908d98e, but my builds don't run every day.

In my Dockerfile I reverted to rustlang/rust:nightly@sha256:b89d3995935b220fddcb8d8496224c722a83140e6a2f88e61c371378f63fb08d, which is from a week or two ago, and my build pipeline works again. And yes I am building cargo-leptos prior to my application build (that's another story) as opposed to downloading the binary.

I know this probably isn't a cargo-leptos issue, just pointing it out in case others run into it.

At first I thought this issue was fairly isolated to cargo-leptos which is why I filed this, but I've since discovered more build hang or overflow situations with other projects. Its clearly not isolated to this project. Feel free to close.

This helped me fix my build issue! Ive been banging my head thinking it was something in my config

I've run into it as well, been restarting it a few times and letting it run for an hour, thought it was an issue with my machine. Seems like it's not, thanks for letting others know!

Thanks for posting this!

Has anybody tried any newer nightly builds? Or @benwis can you give any insights here?
