Re: core dump when parsed VoIP call with text media

[Sergey Safarov <s.safarov () gmail com>]

I compiled wireshark with disabled optimization and then created core file.
Then I read core using command
gdb /usr/local/wireshark/bin/wireshark core.20221 -ex "set pagination off"
-ex bt -ex "bt full" -ex quit

Output published here http://217.12.247.220/tmp/wireshark-gdb.html
Could you have a look.
