Wireshark · Wireshark-dev: Re: [Wireshark-dev] master branch of Wireshark/tshark hangs

[Remy Leone <remy.leone@xxxxxxxx>]

I'm not sure to understand. Wireshark doesn't crash but hangs in that case. How could I get a symbolized stack trace?

I've tried before to use libtool --mode=execute gdb ./wireshark but wireshark keeps hanging and I don't know how to use it to get meaningful information.

Best regards

It could be a bug in the Qt GUI component of Wireshark. Is it possible
to attach a debugger to "wireshark" or "dumpcap" and obtain a symbolized
stack trace?

Kind regards,
Peter
