Run the following program on Redhat 7.1 SMP Linux box with latest ladybird (b24):

import java.security.SecureRandom;

public class TestString{
        public static void main(String[] args){
                SecureRandom rng = new SecureRandom();
                byte[] array = new byte[1];
                int index = 0;
                String testString = null;
                char testChar;
                StringBuffer buffer = new StringBuffer();
                do {
                        rng.nextBytes(array);
                        try{
                                testChar = new String(array, "US-ASCII").charAt(
0);
                        } catch(Exception e){
                                continue;
                        }
                        if (Character.isLetterOrDigit(testChar)) {
                                buffer.append(testChar);
                                if (buffer.length() == 8) {
                                        break;
                                }
                        }
                } while ( true );

                String string = buffer.toString();
                System.out.println("String == " + string);
                System.out.println("String length == " + string.length());

        }

}

I got intermittent error message:

String == hAv0w2Ve
String length == 8

Good bye.

This happens about 1 out of 5 runs on RH 7.1 SMP, but not reproducible on
uniprocessor kernel. Although the crash seems to happen after the Java program
is all finished, the crash might make it difficult to check return code after
launching Java in a script or another program.
