Comment 2 Michal Hlavinka 2010-06-07 10:00:16 UTC 
problem is in stringmap implementation (stringmap.c) when removing some node from the tree, node itself is deallocated, but parent's pointer remains set. This results to pointer with free(ed) memory.

patch to fix this

I need it working, so I've prepared this patch. It adds pointer to parent that is used to reset lesser/greater pointer when freeing appropriate sub-node.

btw, usage/help output mentions ... [-N net/mask] but correct is:
-F net/mask --- show traffic flows in/out of network
-N --- don't convert port numbers to services
