Bug

Running the blackbox function solver in newer versions of rust (1.69+) will give an error such as:

thread 'main' panicked at 'misaligned pointer dereference: address must be a multiple of 0x8 but is 0x558d586c8774',

This is due to a bug in wasmer, the tracking issue is noted here

Reproduce

You can reproduce by creating a fresh binary project, importing acvm 0.24.1 and running the following code:

fn main() {
    println!("Hello, world!");
    #[allow(deprecated)]
    let _blackbox_solver = acvm::blackbox_solver::BarretenbergSolver::new();
}

Environment

• Rust 1.72

Similar to circom-compat, we can add a note in the readme until that issue is resolved. See here

I tried to reproduce it on #520 but perhaps something is getting cached during testing -- would like to investigate why that is passing

If I run the nargo built from noir-lang/noir#3353 then I don't run into this issue. @kevaundray can you test and confirm if you still experience this?
