Hi,

When I was trying to decode the reg_rsp message, I got the following message in
wireshark gui.

"[dissector bug: proto.c:932: failed assertion "dissector_assert_not_reached"]"

And it is not dissecting the packet anymore.

I found that there is a missing break statement in switch case which caused the
above bug. Missing break statement location:
Plugins\wimax\msg_reg_rsp.c - line 324

Please let me know is this the correct reason. In my case, I added the break
statement and everything is ok now.

Correct me if I am wrong.

Thanks,
Mohan
