[ns] question about memory management

[cazeau phil]

Hi,

I'm not sure to understand this part: " The []free
method frees a packet by returning it to the free
list. Note that packets are never returned to the
system's memory allocator. Instead, they are stored on
a free list when []Packet::free is called. "

In that case (" packets are never returned to the
system's memory allocator ") how is it possible to
clean the used memory during segmentation fault?
Is it the function of the PURIFY ns-method ?
if yes  how can I use it?

Thank you,
I really need some help or advice to debugg a
segmentation fault...

ciao
