oakc will compile the following code. When it is run it causes the
interpreter to SEGV. I am not sure if the situation is detectable at
sompile time or not,. This bug may have to be refiled againats the
interpreter.

 
class AbstractBugClass {
 
    abstract int read();
}
 
class BugClass extends AbstractBugClass {
 
    public int read() {
        return super.read();
    }
 
    public static void main(String args[]) {
        BugClass b = new BugClass();
        b.read();
    }
 
}

This is partly a compiler problem, it should not allow this
invokation. But the interpreter should not SEGV.
