This type of thing is very likely indicative of some memory corruption in your code. It's unlikely to be in gtk (but could be). Just the fact that removing the second pointer declaration makes it work indicates that it's your code that's messing up somewhere. Just declaring a pointer doesn't do any object initialization (ie gtk_tree_view_new type stuff). What it does do is change your stack layout slightly such that whatever memory corruption you're doing won't cause an immediate crash when you remove that unused variable. Adding it back in changes offsets just slightly so that something important on the stack is overwritten. Pointer errors always maifest themselves in this type of manner. Very frustrating. Good luck. You'll want to run your code through DDD debugger. It has some very powerful facilities for viewing your variables etc. You can then watch what happens when the offending line is executed. Also you can load the core file into the debugger after the fact and see what line triggered the core dump, see the variables, etc. Should help you establish what's happening. (DDD is run by the command ddd. It's downloadable from the internet too -- see freshmeat.net) Michael > > > > _______________________________________________ > gtk-app-devel-list mailing list > gtk-app-devel-list gnome org > http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list -- Public key available from http://students.cs.byu.edu/~torriem
