patch

This patch gets rid of the segfault and is free of regressions. However, the
dump still shows a double nullification of the 'label' component:

      appv->label = 0B;
      {
        struct branch_plot_results_ppv_type branch_plot_results_ppv_type.0;

        if (appv != 0B) goto L.1;
        appv = (struct branch_plot_results_ppv_type *) __builtin_calloc (1, 8);
        L.1:;
        branch_plot_results_ppv_type.0.label = 0B;
        *appv = branch_plot_results_ppv_type.0;
      }
