A single packet that will crash Wireshark in the gsm_map dissector.

Build Information:

Load the attached .pcap file.  Wireshark will crash.  This bug was discovered
while fuzzing the menagerie for testing some recent changes I made; however,
the crash occurred in a completely different place, namely packet-gsm_map.c.

I will attach a patch; however, I'm not too familiar with asn1 so maybe someone
could apply the right fix to the right file in the asn1/gsm_map/ directory and
regenerate packet-gsm_map.c?
