 You may close this bug.  I have confirmed that it was fixed sometime
 between gcj3.2 and HEAD-13-May-2003.  The included how-to-repeat
 program executes properly.

 Hello,
 
 this PR was submitted over a year ago, and has had no feedback since.  
 Has there been any progress on this problem? Is this problem still  
 present in current gcc souces? Thanks,
 
 Dara

>Description:
The program below prints out
"0" rather than "3". Closer inspection reveals that foo() is looking
at a memory location four bytes less than wher y is. This behavior
occurs on both Win32 and Linux.

>How-To-Repeat:
cat > test.java <<\EOF
abstract class sup {
    long a;
    boolean b;
    public sup() { }
}

public class test {

    public static void main(String[] s) { new inner(); }

    static class inner extends sup {
        int y = 3;
        native void foo();
        inner() { foo(); }
    }

}
