Input in.zip

Code

fn main() {
    // let filepath = input file in the zip
    let data = std::fs::read(filepath).unwrap();
    if let Ok(vm) = rbpf::EbpfVmNoData::new(Some(&data)) {
        vm.execute_program();

    }

    
}

Output

Looks the same as https://github.com/qmonnet/rbpf/issues/94, which should hopefully be addressed in https://github.com/qmonnet/rbpf/pull/98.
