Dissector Bug in MBMS Bearer Event AVP

[Dincer Beken <dbeken () blackned de>]

Hello all,

I am using wireshark 3.0.6 and I am trying to decode the MB2c Diameter Protocol for LTE Multicast (eMBMS). In the 
capture in the attachement, when I want to sent the MBMS Bearer Event AVP in the Diameter MB2C GCS-Notification-Request 
message, i get an Dissector Error. It does not like what II put into the MBMS-Bearer-Event, no matter the value is.

Could you tell me if that is a bug, or if the value is wrong? I have tried, 0x0, 0x1, 0x80, 0xFF etc.. all resulted in 
the parsing bug.

The specification says the following:

[cid:c8d76ea4-3f50-463a-84e4-e5a2fb4dff0f]

The error: is epan/proto.c:10950 failed assertion "hf->bitmask!=0" (Diameter.3gpp.mbms_bearer_event_spare).

[cid:439ded01-2818-4b99-afc8-bd2d6e7b67d0]


Regards,
Dincer
