little issue in the binpack.c

[uurlasrl]

Hi,
I think there is a little issue in the binpack.c source code line 628

...
if ( smallestz->next->next )
{
smallestz->prev->next = smallestz->next->next;
smallestz->next->next->prev = smallestz->prev;
free(smallestz);
}
...

should be
...
if ( smallestz->next->next )
{
smallestz->prev->next = smallestz->next->next;
smallestz->next->next->prev = smallestz->prev;
free(smallestz->next);
free(smallestz);
}
...

right?

Regards
Domenico
