[BUG] APM profiler-based auto instrumentation causes applications to crash when accessing satellite assemblies for resources

[stevejgordon]

APM Agent version

1.27.0

Operating system and version:
Windows 11

.NET Framework/Core name and version: .NET 4.8

Describe the bug

If the APM automatic instrumentation is enabled against an ASP.NET (.NET Framework) application that uses resources in satellite assemblies, the app crashes multiple times. Eventually, it will usually start sending trace and metric data. This is reproducible for me locally. It seems the trigger is the load of the satellite assembly containing resources. As soon as code runs which accesses a resource, the crash occurs.

To Reproduce

1. Create a ASP.NET WebApi project.
2. Add MyResources.resx and MyResources.en-US.resx files

3. Add a single string and value

4. Consumbe the resource in code

public class HomeController : Controller
{
    public ActionResult Index()
    {
        CultureInfo originalCulture = Thread.CurrentThread.CurrentCulture;

        try
        {
            CultureInfo newCulture = new CultureInfo("en-US");
            Thread.CurrentThread.CurrentCulture = newCulture;
            Thread.CurrentThread.CurrentUICulture = newCulture;

            ViewBag.Title = MyResources.Test;
        }
        catch (CultureNotFoundException e)
        {
            Console.WriteLine("Unable to instantiate culture {0}", e.InvalidCultureName);
        }
        finally
        {
            Thread.CurrentThread.CurrentCulture = originalCulture;
            Thread.CurrentThread.CurrentUICulture = originalCulture;
        }

        return View();
    }
}

5. Deploy the app to IIS and observe it starting without issue
6. Enable profiler auto instrumentation per this doc
7. After recycling the app pool, as soon as the first code accesses a resource (i.e. a request hits the home controller above), the app will often crash at least once. It generally eventually recovers after several crashes.

The crash can be captured using tools such as DebugDiag. When a rule is active against the app pool, one will often observe at least one crash.

Expected behavior

The application starts without crashing.

Actual behavior

The application often crashes.
