Here is another phenomenon:
>From the following class,
If you put
int i = b ? 1 : 0;
before the
System.out.println("1 - now: " + b);
it is wrong. Result:
1 - now: false
i is: 0
2 - now: true
3 - is i > 0? true
(i is not > 0).
But, if you put the println first, the result is corrent. (3 - is i > 0?
false).
Must use -Os: gcj --main=gc -Os gc.java

import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
public class gc
{
static public void main (String[] s)
{
bla(false);
}
static void bla(boolean b) {
int i = b ? 1 : 0;
System.out.println("1 - now: " + b);
System.out.println("i is: " + i);
try {
Socket socket = new Socket("localhost", 8888);
} catch (IOException e) {
System.out.println("2 - now: " + b);
bla2(i > 0);
}
}
static void bla2(boolean b) {
System.out.println("3 - is i > 0? " + b);
}
}
