Not exactly. Quite reasonably, you could write some code, link it to libxml1 and libxml2 both, so that it would crash: I would not consider this a bug. What is happening here is that there is some code, linked to gtk2.0 and libxml1, that crashes; and this is unpredictable, since gtk2.0 is not linked to libxml2. So this is a bug. The problem AFAICT is that the 'fails' binary uses gtk_file_chooser_button and then in GTK (*) there is a call to gtk_file_system_gnome_vfs_new () that invokes gnome, that uses libxml2 ; since 'fails' is linked with libxml version 1, this malfunctions. It may be a bug in the way the libxml2 is dl_opened , and it is linked.
