Ethereal-dev: Re: [Ethereal-dev] Bug report for ethereal-0.10.10 on Fedora x86_64 version
I've reproduced this bug on x86_64 machine as well. Running ./ethereal -
i any -kS segfaults, backtrace on nonoptimized ethereal shows
(gdb) bt

Looking into capture_ui_utils.c I really don't know why it started to
fail while AFAIK there weren't any changes recently :(
