Error compiling with PostSharp 4.3.20

When I try to compile from inside Visual Studio 2015 I am getting the following error trace. Has anyone else experienced this?

Error       Unhandled exception (4.3.20.0, postsharp-net40-x86-srv.exe, CLR 4.0.30319.394271, Release): System.NullReferenceException: Object reference not set to an instance of an object.

Edit: In attempting to produce a sample project for this I was able to isolate the cause. We had an OnMethodBoundary aspect (an in-house logging one) applied to a type with public static implicit operator T(Editable<T> item). When I told PostSharp to exclude this method the problem went away.

So to reproduce it, apply an OnMethodBoundary to a generic implicit operator, while using an Express license.

[ExceptionLoggerAspect]
class Challenged<T>
{
    public T Value { get; set; }

    public static implicit operator T(Challenged<T> item)
    {
        return item.Value;
    }
}

The work-around I ended up using was to use AttributeExclude = true on a generically typed implicit operator, which our OnMethodBoundaryAspect was being multicast on to.

[ErrorLoggingAspect(AttributeExclude = true)]
public static implicit operator T(Editable<T> item) 
{ 
  ... 
}
