  <pre><code>class Program
  {
          private int? m_bool;
          private bool prop {get{ return false;}}
          void test()
          {
              //nothing
          }
          private object Test()
          {
              if (prop)
              {                    
                  try
                  {
                      test();
                  }
                  catch (Exception) {}
  
                  m_bool = 1;                    
              }
              return null;
          }
  
          static void Main(string[] args)
          {
              new Program().Test();
          }
  }

  <p>Seems the similar issue is <a href="https://github.com/dotnet/coreclr/issues/10826" rel="noreferrer">https://github.com/dotnet/coreclr/issues/10826</a></p>
  
  <p>Anyone knows how to avoid that?</p>
