Summary

the following snippet will crash 100% of the time.


foo <public> := class{ I : int = 0 }
   

tester_component <public> := class<final_super>(component):
    
    FooEvent : event(foo) = event(foo){}
   
    OnSimulate<override>()<suspends>:void=
    
        Temp : foo = foo{}

        EventTask : task(foo) = spawn{ FooEvent.Await() }

        branch:
            Sleep(1.0)
            FooEvent.Signal( Temp ) # <- causes crash but compiles fine. 

        Foo := EventTask.Await() 


### a temp workaround ###

<#

    This seems to work just fine from what I can tell. 

#>

awaitable_task_wrapper<internal>(t:type) := class<internal>:
    Awaitable <public> : awaitable(t)
    AwaitValue<internal>()<suspends>:t=(Awaitable.Await())

(Awaitable:awaitable(t) where t:type).Task<public>():task(t)=
    Wrapper := awaitable_task_wrapper(t){ Awaitable := Awaitable }
    spawn:
        Wrapper.AwaitValue()
