EnumerableRewriter.FixupQuotedArgs(MethodInfo, ReadOnlyCollection`1<Expression>) initiated call, 
intended callee was RuntimeMethodInfo.GetParameters(), 
actually observed callee was Array.Copy(Array, Array, Int32),
and arguments of intended callee don't match actual callee;
did some intermediate methods not get instrumented?
See the help for further information.
