Wireshark-dev: [Wireshark-dev] Fix bug in GSM MAP, have problems with GIT
From: Anders Broman <a.broman@xxxxxxxxxxxx>
Date: Sat, 08 Mar 2014 09:45:21 +0100
Hi,Could some one replace the file in asn1/gsm_map with this one, and regenerate the dissector?
"Omitting SubscriberData makes CONTENT OF fail and InsertSubscriberDataArg will not get all its tags"
Best regards Anders

# characters (A-Z and a-z), digits (0-9) and the hyphen (-). Following RFC 1123 [20], the label shall begin and end with
