glibc detected *** double free or corruption

Hi,

I'm trying the "apache_chunked_win32"-exploit, but I get that error  
after a few trys:

        [*] Trying Apache.org Build 1.3.17->1.3.24 (Windows 2000)  
[ 0x1c0f13e5/7 ]
        ....
        *** glibc detected *** double free or corruption (!prev): 0x09570ad8  
***

What does that mean?

Greetings,
Sebastian
