Problem with gtk_im_context_get_surrounding ()

["Aleksey A. Malyshev" <maa sparc spb su>]

Hi,

I have a problem with gtk_im_context_get_surrounding ().

Test case:
#include <gtk/gtk.h>

int
main (int argc, char** argv)
{
    GtkIMContext *context;
    gint *index;
    gchar **text;
    gboolean res;

    gtk_init (&argc, &argv);
    
    context = gtk_im_multicontext_new ();
    
    res = gtk_im_context_get_surrounding (GTK_IM_CONTEXT(context),text ,index);
    if (res)
        printf ("\nResult True\n");

}

Output:
Segmentation fault


What's wrong in this case?
What I am doing wrong?

Thanks,
    Aleksey.
