VM crashes with Segmentation Fault when run JavaTest executed JCK-12beta2 test
lang/clss212/clss21201/clss21201 under sameJVM.

> java -version
java version "1.2beta4"
Classic VM (build JDK-1.2beta4-J, green threads, sunwjit)

> java javasoft.sqe.javatest.tool.Main t20.jck12beta4.jtp &
[1] 11001
[1] Segmentation Fault java

JDK-1.2beta4-G shows the same result.

The bug is still reproduced with JIT switched off under jdk1.2beta4K, jdk12fcsK, jdk12fcsL.
To reproduce run the test using the following driver program that simulate
JavaTest harness slave:

-----------------------trun.java---------------------------
import java.io.PrintStream;
import javasoft.sqe.tests.lang.clss212.clss21201.clss21201;

public class trun implements Runnable {
  public static void main(String argv[]) {
   trun x = new trun();
   Thread child = new Thread(x);
   child.start();
        try {
child.join();
}catch (Throwable e){};
  }
  public void run()
  {
System.out.println("START");
clss21201 rec=new clss21201();
rec.run(null, System.out);
System.out.println("END");
  }

}

Other bug revealed with the test is that VM loads javasoft.sqe.tests.lang.clss212.clss21201.clss21201
successfully from the main thread but throws StackOverflowError when the class is loaded from
a secondary thread (as in trun.java). See also Bug Id 4139375 (Synopsis: main and child threads
have different stack sizes on VM with JIT.)
