Problem with memoryleak in octstr

[Ken A. Redergård]

Hi,
I'm trying to figure out why the following octstr function leak 1 byte 
of memory for each iteration:

/* test_octstr.c */
#include <unistd.h>
#include "gwlib/gwlib.h"
int main(void) {
 Octstr *os;
 int i;
 gwlib_init();
 for (i = 0; i < 100; i++) {
   os = octstr_format("sadfasdfasdfas");
   octstr_append(os, octstr_imm("asdfasdfasdfasdf"));
   octstr_destroy(os);
   gwthread_sleep(1);
 }
 gwlib_shutdown();
 return 0;
}
Watching this with "ps -C test_octstr -F" shows that for every four 
seconds it leaks 4 bytes... Is the use of octstr incorrect or is it a 
problem in gwlib ?

With regards,
-Ken.
