Thread core dump

[ymaekawa@trd.tmg.nec.co.jp]

Hi,

I have compiled egcs and libgcj sources of snapshot(1999-04-05).
and installed on Solalis.

Then I have compiled simple java thread program like below.
and run it. then, I get a core dump.

What's wrong?
------------------- execution result
65 trds500% make
gcj   -c -o Main.o Main.java
gcj --main=Main -o main Main.o -lgcj -lgcjgc

------------------- Test program
public class Main {
   public static void main(String[] a) {
      new Green().start();
      new Red().start();
      new Yellow().start();
   }
}
 
class Green extends Thread {
   public void run() {
         do {
             System.out.println("Green Thread");
	     yield();
         } while (true);
   }
}

class Red extends Thread {
   public void run() {
         do {
             System.out.println("Red Thread");
	     yield();
         } while (true);
   }
}

class Yellow extends Thread {
   public void run() {
         do {
             System.out.println("Yellow Thread");
	     yield();
         } while (true);
   }
}
