Please describe the problem:
When functions return array, and there is local variable with name "result" in function then there two declarations of result_length1 in generated code.
First declaration for returned array length (in function parameters) and second in function body for length of variable "result".
Changing variable name from "result" to "res" fixes the problem

Steps to reproduce:
class TestResult{
  int[] doubleArray(int[] arr){
    int[] result = new int[arr.length];
    for(int i=0; i<arr.length; i++)
      result[i] = arr[i]+arr[i];
    return result;
  }
  
  int main(string[] args){
     int[] arr = {1,2,3};
     int[] doubled = doubleArray(arr);
     return 0;
  }
}
