Wireshark-dev: Re: [Wireshark-dev] [PATCH] stats_tree.c fixup preventing segfault
Hi Stephen,
it's just after ... I leave the filter empty and click create stats :)
see in the code plugins/pinfo_stats_tree.c line 97 :
st_node_plen = stats_tree_create_range_node(st, st_str_plen, 0,
"0-19","20-39","40-79","80-159","160-319","320-639","640-1279","1280-2559","2560-5119","5120-",NULL);
Anyway, when you asked me how to reproduce it did not crash anymore
(ouchh...). Strange.
However, I remember that I got rid of glib/gtk1.2 yesterday to finally
arrive to something which seems really better, in terms of graphical
interface, gtk+2 (even if I'm merely a command line lover :)) And it
appears that this "slight" change made wireshark more robust or maybe I
was just concerned by an hallucination? :-/
I therefore installed again (just for you :)) glib/gtk1.2 and start a
new compile process (tooooo long) to see what happens ... and here is
one config on which it crashes :
