            Bug ID: 259441
           Summary: WASM module memory errors
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebAssembly
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jerome+webkit at eventuallyconsultant.com

We had a weird bug using Tauri + Leptos (Rust/WASM) framework.
Those are using the system webview in order to run a UI (Electron style ... but without chrome)

On our linux machines (Ubuntu or Fedora), it randomly crashes.
more details here : https://github.com/rustwasm/wasm-bindgen/issues/3470

Narrowed it with this very light example : https://github.com/jrouaix/wasm_pbm
- this is 100% sure NOT related to Tauri
- we also reproduced it without Leptos

Do you folks have an idea where I should dig more or ask for help in order to resolve the issue ?
(i'm very surprise to be the first to step into something so easy to reproduce)
