Everytime i close (hit the X with the mouse) ethereal, the program core dumps (SIGBUS). This happens eveytime i close the program this way. It looks like the gtk lib is doing something bad with a window reference. A check is made in the code if the window pointer is != NULL, if so a call is made into the gtk lib with the pointer value as the first argument. I did a litle amateur debugging, here are the traces: root~#uname -a FreeBSD volvo.tomten.homelinux.net 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Sun Nov 17 23:11:17 CET 2002 root@volvo.tomten.homelinux.net:/usr/obj/usr/src/sys/KERNEL10 i386 root~#pkg_info | grep gtk gtk-1.2.10_9 Gimp Toolkit for X11 GUI (previous stable version (gdb) info breakpoints Num Type Disp Enb Address What 1 breakpoint keep y 0x08203a38 in main at main.c:2024 2 breakpoint keep y 0x08203a3d in main at main.c:2042 3 breakpoint keep y 0x08202987 in main at main.c:1201 (gdb) run Starting program: /usr/ports/net/ethereal/work/ethereal-0.9.7/.libs/ethereal Breakpoint 3, main (argc=1, argv=0xbfbff864) at main.c:1201 (gdb) p top_level $1 = (struct _GtkWidget *) 0x0 (gdb) list 1196 #endif 1197 char *s; 1198 int i; 1199 int opt; 1200 extern char *optarg; 1201 gboolean arg_error = FALSE; 1202 #ifdef HAVE_LIBPCAP 1203 #ifdef HAVE_PCAP_VERSION 1204 extern char pcap_version[]; 1205 #endif /* HAVE_PCAP_VERSION */ (gdb) c Continuing.
