Visual studio project showing bug

I am using Evaluator.Evaluate to return a Func. Inside that func i declare a variable, then another func which attempts to use this variable. Trying to use the variable inside a new Func causes an Internal Compiler Error

This is caused by not cloning LocalInfo's, it then points to wrong (not cloned) block. Changing this would require to make same extra cloning of TopLevelBlock names cache as we do for labels.

This can be workarounded by assigning the new to variable. E.g. changing the code to

"var temp = new Func<int>(()=>{"+......
