Running the following program with Mono will crash

using System;
using System.Threading;
using System.Reflection;

namespace X
{
    class Program
    {
        static void Main(string[] args)
        {

	    Thread.CurrentThread.Name = "Main-Thread";
	    
	    AppDomain.CurrentDomain.AssemblyLoad += (_sender, evt) => {
		var assm = evt.LoadedAssembly;
		var name = assm.GetName();
		// removing this line fixes the crash
#if true
		Console.WriteLine ($" : Loaded {name.Name} from '{assm.Location}' on {Thread.CurrentThread.Name}");
#endif
	    };
	    
	    var allDone = new ManualResetEventSlim ();
	    var proceed = new ManualResetEventSlim ();

	    var conflictThread = new Thread(() => {
		proceed.Set();
		Console.WriteLine ($" - {Thread.CurrentThread.Name} waiting for all done");
		allDone.Wait();
	    });
	    conflictThread.Name = "Conflict-Thread";
	    conflictThread.Start();

	    proceed.Wait ();
	    allDone.Set ();
	    Thread.Sleep (1000);
	    Console.WriteLine ($" {Thread.CurrentThread.Name} exiting");
        }
    }
}

Expected Output: no crash

Actual Output:

[lambdageek]

@CoffeeFlux I suspect this is happening because CoreCLR doesn't call OnAssemblyLoad for "system" libraries and we do (I think?)

runtime/src/coreclr/vm/appdomain.cpp

Line 4232 in 3e8884c

if (pAssembly->GetFile()->IsSystem())

("IsSystem" is basically CoreLib, as far as I can tell... PEAssembly::OpenSystem is I think the only thing that sets that flag to true)

[CoffeeFlux]

Wouldn't surprise me - there are various "are we corelib" checks present in the loading algorithm and I could easily have missed one. We should probably add a test for this too.

[CoffeeFlux]

Was this prompted by a real user crash or anything else I should know about? How did you even find this? Trying to prioritize.

[lambdageek]

Actually I think this isn't due to "IsSystem" it's due to the EX_TRY/EX_END_CATCH(SwallowAllExceptions) wrapper around the invoke. I bet CoreCLR has the exception too, and just swallows it. I'll try the same thing on Mono, see what happens.

Was this prompted by a real user crash or anything else I should know about? How did you even find this? Trying to prioritize.

I was working on a repro for mono/mono#21032 / #51864 - a deadlock between a managed lock and the runtime loader lock that VSMac sometimes hits - and trying to repro on .NET 6 Mono I hit this assert instead of the deadlock that I was expecting.

[lambdageek]

hmm just catching and ignoring the managed exception in mono_domain_fire_assembly_load doesn't work. Because by that point we already marked the TerminalFormatStrings class as failed with a "Recursive type definition detected" error.

So the next call to System.Console is going to fail too.
