Repro by the following code.
This will fail since the process doesn't have SYS_PTRACE, but the problem is that any error that is thrown there will cause an access violation and kill the process.
I believe that the issue is something with the way the code jumps between managed / native codes there that isn't ready to handle exceptions, but I'm not sure

try
{
    var dt = DataTarget.AttachToProcess(Process.GetCurrentProcess().Id, 1000, AttachFlag.Passive);
    var runtime = dt.ClrVersions[0].CreateRuntime();
    var st = runtime.Threads[0].EnumerateStackTrace().First();
    Console.WriteLine(st.DisplayString);
}
catch (Exception e)
{
    Console.WriteLine(e);
    Console.WriteLine("Error, died");
}
