The "0x00000000077ec30" value looks like an address, probably the address of the code that made the double free() call. To find out who's responsible for that code, you need to find out where it comes from.

Add these lines before your return call:

Code:
#include <sys/types.h>
#include <unistd.h>
#include <stdio.h>

char command[ 1024 ];
long pid = ( long ) ::getpid(); // use long to ensure correct format specifier
sprintf( command, "pmap %ld", pid );
system( command );

That will cause the pmap utility to be run against your running process. The address value "0x00000000077ec30" should fall within a range of one of the objects in the memory map you'll see as output. That should tell you who is responsible.
