In:
void user_entered_string(GtkWidget *window)
    {
    user_has_clicked = 1;
    user_clicked_value = 1;
    strncpy(entry_text, gtk_entry_get_text(GTK_ENTRY(entry)),
      ENTRY_TEXT_LENGTH);
    entry_text[ENTRY_TEXT_LENGTH - 1] = '\0';
    gtk_widget_destroy(window);
    }

from gtk.c, there is an uninitialized usage of the entry_text pointer.
This pointer is never set. There is a possible harmful usage of calloc
in gtk_specific_init, but it didn't run at all here.
