Overflow errors when trying to build

[marstaik]

Hi all, building rust-gpu on my machine and I'm getting these potential overflow warning checks thrown.

Let me know if there is anything else I can provide

I moved it to rust-gpu for better visibility by the other users and maintainers.

I actually have never seen it error like that. If you're using rust-gpu directly (without cargo-gpu) you could work around this issue by adding default-features = false, features = ["use-installed-tools"] to the spirv-builder dependency and installing the vulkan sdk on your system.

I've never seen that myself either 🤔
