Error glibc detected

[stex83]

Hello
This is the class MyExposeListener:

import org.gnu.gtk.event.ExposeEvent;
import org.gnu.gtk.event.ExposeListener;
import com.irex.mobipocket.reader.Utils;
import com.irex.sdk.DisplayUpdate;

public class MyExposeListener implements ExposeListener
{
public boolean exposeEvent(ExposeEvent arg0)
{
if(arg0.isOfType(ExposeEvent.Type.EXPOSE))
{
System.out.println("refresh");
DisplayUpdate displayupdate = DisplayUpdate.getInstance();
displayupdate.dispMainWinFullQ();
}
return true;
}
}

This class is invoked as an event by the constructor of class TextBuffer:

w.addListener(new MyExposeListener());

The class TextBuffer runs and sometimes returns following errors and the program ends its execution:

1) *** glibc detected *** /usr/lib/jvm/java-1.4.2-gcj-4.1-1.4.2.0/bin/java: double free or corruption (!prev): 0x08082918 ***
2) *** glibc detected *** /usr/lib/jvm/java-1.4.2-gcj-4.1-1.4.2.0/bin/java: double free or corruption (fasttop): 0x0822f898 ***
3) *** glibc detected *** /usr/lib/jvm/java-1.4.2-gcj-4.1-1.4.2.0/bin/java: double free or corruption (out): 0x08254d98 ***
4) *** glibc detected *** /usr/lib/jvm/java-1.4.2-gcj-4.1-1.4.2.0/bin/java: free(): invalid next size (fast): 0x0821dfa0 ***
5) *** glibc detected *** /usr/lib/jvm/java-1.4.2-gcj-4.1-1.4.2.0/bin/java: free(): invalid pointer: 0x080abf60 ***

These errors depend from the instruction:

w.addListener(new MyExposeListener());

because without this instruction I have no errors during the execution.

How can solve this problem?
Thanks

I solved by eliminating class MyExposeListener and inserting instruction DisplayUpdate.dispMainWinFullQ() at the end of class TextBuffer.

That's an old Linux C++ error. Not new news.
To fix it so you can run the program just type:

export MALLOC_CHECK_=0

before running the program.
