Best way to get it fixed is to file a bug with a small repro.

Thanks,

Thanks for the tips, Curt, JB. I’ll file a bug report with Novell and  
hope Marek can build a repro himself. I’m currently stealing time  
just to run the build and report errors, so I don’t really have time  
to go too deep here.

Cheers,

C.J.

\_traceListener.Call(new[] {  
MutableString.Create(“call”), // event  
fileName, // file  
RuntimeHelpers.Int32ToObject(lineNumber), // line  
scope.Method.DefinitionName, // TODO: alias  
new Binding(scope), // binding  
module.IsSingletonClass ? ((RubyClass)module).SingletonClassOf :  
module // module  
});

I suspect that the Mono compiler is choking on the mix of reference  
types with one value type in the array – the compiler will need to box  
DefinitionName to put it into an object[] array. That should help you  
devise a repro.

I imagine you could force this to build by manually casting  
DefinitionName to an object.
