wireshark crash with segmentation fault

[Hardik Patel <hardik.party () gmail com>]

Hi,

I come accross a problem in which some time wireshark crash and i can see
"segmentation fault" on console.

i have created dissector in which i guess problem with tree struct and ett
variables, i think i have not properly define.

I read that *The expansion of this node is controlled by the ett_foovariable.
*

for example i click on packet frame which have long tree and than i move
directly to packet frame which has smaller tree. so i guess wireshark
remember that last time i have open 5th element of tree but this time
packet frame do not have 5 element so it crash.

below is those two packet frame in snapshot.

and second has packet frame has only three elements on tree:

so i dont want wireshark to remember what i have opened last.


Thank you very much.
