Virtual machine crashes when executing the csp exmaple

[Embedded Systems Engineering]

Dear CSP community Hello,

I am new to CSP, I am trying to execute the example in this git for client-server protocol.

https://github.com/libcsp/libcsp

csp_server_client.c example.

I am running this example on a virtual machine and when I execute these lines my machine crashes and reboots.

  /* Wait for execution to end (ctrl+c) */
  while (1)
    {
      sleep (3);

      if (test_mode)
    {
      /* Test mode is intended for checking that host & client can exchange packets over loopback */
      if (server_received < 5)
        {
          csp_print("Server received %u packets\n", server_received);
          exit (1);
        }
      csp_print("Server received %u packets\n", server_received);
      exit (0);
    }
    }

Do you have any idea about this issue?

Normally, the code should run il a loopback if any device is connected to my host computer.

Thank you in advance for your help
