SIGSEGV (and than Illegal instruction) on Debian 9.0 x64 Celeron

Core: .NET Core 2.0.5
Kernel: Linux 4.9.0-6-amd64 #1 SMP Debian 4.9.82-1+deb9u2 (2018-02-21) x86_64 GNU/Linux
CPU: Intel(R) Celeron(R) CPU J3455 @ 1.50GHz, 4GB RAM, 25GB
(Mini PC)

Self contained package produced with "dotnet publish -r linux-x64" finishes with illegal instruction after exception.

Code to review:

using System;

namespace App1
{
    class Program
    {
        static void Main(string[] args)
        {
            try {
                String a = null;
                Console.WriteLine(a.Length);
            }
            catch(Exception ex){
                Console.WriteLine(ex);
            }
            Console.WriteLine("Bye");
        }
    }
}

Expected behavior: Print exception and Bye.

Actual behavior:

System.NullReferenceException: Object reference not set to an instance of an object.
   at App1.Program.Main(String[] args) in /home/repomaster/App1/Program.cs:line 11
