Description

The generation of method guard runtime checks causes compilation errors:

public class XTENLANG_2451 {
  public static def main(argv:Array[String]) {
    Console.OUT.println(argv(0));
    async { Console.OUT.println(argv(0)); }
    val a : Array[Int] = [0];
    at (here.next()) {
      a(0) = 1;
    }
  }
}

results in

./XTENLANG_2451.x10:4: Cannot return from an async.
./XTENLANG_2451.x10:7: Cannot return value from void method or closure.
./XTENLANG_2451.x10:7: Cannot return a value from at in ./XTENLANG_2451.x10:6,5-8,5.
3 errors.

And even something as simple as

public class XTENLANG_2451 {
  public static def main(argv:Array[String]) {
    Console.OUT.println(argv(0));
  }
}

produces post-compilation errors:

x10c: ----------    
     1. ERROR in ./XTENLANG_2451.java (at line 17)    
        main_0_$_x10$lang$String_$(    
     final x10.    
     array.    
     Array<java.lang.String> argv){    
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^    
     This method must return a result of type Object    
     ----------    
     1 problem (1 error)

and, even more cryptic:

x10c++: No main method found
