Hi,
Make sure you are well handling packets. In fact if you forgot to drop
or to resume a packet in a procedure this will be accumulated and will
lead to a segmentation fault or bus error. Also if you make an operation
on a null or already dropped packet this may also invoke this error.
When you pass a packet to another layer, you own no more this packet so
you must no more process it.
Hope this will help.
Paul.
