Version: 13.0.2(com.unity.nuget.newtonsoft-json@3.2)

Frequency: rarely

Description:

I think the crash is resulted by both Newtonsoft.json and il2cpp, maybe without il2cpp, this code can also throw some exception but can be handle by catch exception.

Here's the log:

Operating system: Android
                  0.0.0 Linux 4.19.157+ #1 SMP PREEMPT Fri Nov 10 04:11:04 PST 2023 aarch64
CPU: arm64
     8 CPUs

GPU: UNKNOWN

Crash reason:  SIGSEGV /SEGV_MAPERR
Crash address: 0x132
Process uptime: not available

Thread 77 (crashed)

Source/destination JSON

{"version":"1.0", "method":"SomeMethod","arguments":{"host":"127.0.0.1","username":"test","password":"test"},"req_id":"xxx","req_time":"xxx"}

Expected behavior

Not Crash

Steps to reproduce

[JsonObject(MemberSerialization.OptIn)]
public class Request<T>
{
    [JsonProperty(Order = -3)]
    private string version;
    [JsonProperty(Order = -2)]
    private string method;
    [JsonProperty(Order = -1)]
    public T arguments;
    [JsonProperty]
    private readonly string req_id;
    [JsonProperty]
    public readonly DateTime req_time;

    public Request(string version, T arg)
    {
        this.version = version;
        this.method = typeof(T).FullName;
        this.arguments = arg;
        this.req_id = Guid.NewGuid().ToString();
        this.req_time = DateTime.Now;
    }

    public string ToJson()
    {
        return JsonConvert.SerializeObject(this);
    }
}

public struct SomeArgs
{
    public string host;
    public string username;
    public string password;
}

int Foo(Request<SomeArgs> req)
{
    Task.Run(delegate
    {
            var des = JsonConvert.DeserializeObject<Request<SomeArgs>>(req.ToJson());
            des.arguments.username = /* Some operation */
            return des.ToJson();
    });
    return 0;

While i am only a user and not a maintainer of Newtonsoft.Json (but moving away from it in favour of STJ), your problem is essentially with the code il2cpp produces. Therefore, you should contact the il2cpp folks and file an issue with them and listen to what they have to say about what you could/should do regarding using il2cpp on a project utilizing Newtonsoft.Json. There is/was a custom 3rd-party modification of Newtonsoft.Json somewhere on github that claims to be compatible with il2cpp, but i don't know it and can't say anything about it. (Also, it will be unlikely to get support and help for a 3rd-party modification of Newtonsoft.Json here in the issue tracker of the official Newtonsoft.Json library.)
