Hi,
Forgot to mention that I am using SVN-Head
The code compiles with the released x10 2.0 c++ backend.
This also runs, but randomly gives exceptions of the form:
Uncaught exception at place 0: x10.lang.NullPointerException

Subject: problem compiling code
Hi,
I have a piece of code (attached below). The code doesn't compile with C++
backend and gives the following error:
x10c++: In file included from actualtest.cc:4:
actualtest.inc: In member function ‘void actualtest__closure__1::apply()’:
actualtest.inc:33: error: invalid use of member (did you forget the ‘&’ ?)
actualtest.inc:33: error: invalid use of member (did you forget the ‘&’ ?)
x10c++: Non-zero return code: 1
2 errors.
With Java backend the code compiles and runs, but randomly gives exceptions of
the form:
java.lang.ArrayIndexOutOfBoundsException
at java.lang.System.arraycopy(Native Method)
at x10.core.GrowableRail.grow(GrowableRail.java:81)
at x10.core.GrowableRail.add(GrowableRail.java:46)
at x10.util.ArrayList.add(ArrayList.java:175)
at actualtest$1.apply(actualtest.java:108)
at x10.lang.Activity.run(Activity.java:169)
at x10.lang.Runtime$Worker$3.apply(Runtime.java:3222)
at x10.runtime.impl.java.Runtime.runAt(Runtime.java:101)
at x10.lang.Runtime$Worker.loop(Runtime.java:3189)
at x10.lang.Runtime$Worker.apply(Runtime.java:3077)
at x10.lang.Runtime$Pool$1.apply(Runtime.java:3408)
at x10.runtime.impl.java.Thread$1.run(Thread.java:36)
at java.lang.Thread.run(Thread.java:619)
Any help is appreciated.
The code:
---------------------------------------
import x10.util.*;
class testIt {
public var i:Int;
public def this(ii:Int) { i = ii; }
}
public class actualtest {
public def this() { }
public def make() {
val strs = new ArrayList[testIt]();
finish for(var i:Int=0; i<100; i++) {
val ii = i;
async { strs.add(new testIt(ii)); };
}
finish foreach(s in strs) x10.io.Console.OUT.println((s as
testIt{self.at(this)}).i);
}
public static def main(args:Rail[String]!) : void {
new actualtest().make();
}
}
---------------------------------------------
In the beginning there was nothing. God said, 'Let there be light!' And there
was light. There was still nothing, but you could see it a whole lot better.
