>Organization:
>Environment:
GCJ-Linux, GCJ-PowerPC, GCJ-Win32
>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.

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

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

}
