Calling java.awt.Choice.insert() 20 times causes
a core dump on Solaris (but not windows).
Sample program: (hit the "ADD" button 20 times)



import java.awt.*;
import java.awt.event.*;

class ChoiceTest extends Frame implements ActionListener {

  Choice c;

  ChoiceTest() {
    setLayout(new FlowLayout());
    Button b = new Button("ADD");
    b.addActionListener(this);
    add(b);
    c = new Choice();
    c.add("Initial choice");
    add(c);
  }

  public static void main(String args[]) {
    ChoiceTest f = new ChoiceTest();
    f.setSize(500,500);
    f.setVisible(true);
  }

  public void actionPerformed(ActionEvent evt) {
    c.insert("new choice!", 0);
  }
}



Output:

SIGBUS 10* bus error
    si_signo [10]: SIGBUS 10* bus error
    si_errno [0]: Error 0
    si_code [1]: BUS_ADRERR [addr: 0xdf80063b]
