status_icon オブジェクトを作成する .c ファイル関数があります。

file.c

void create_status_icon(GtkWidget *app)
{
    GdkPixbuf *pixbuf;
    GtkIconTheme *icontheme;

    icontheme = gtk_icon_theme_get_default();
    pixbuf = gtk_icon_theme_load_icon(icontheme, "application", 22, 0, NULL);
    g_return_if_fail(pixbuf);
    status_icon = G_OBJECT(gtk_status_icon_new_from_pixbuf(pixbuf)); // <-- uninitialized
    g_object_unref(pixbuf);

    g_signal_connect(G_OBJECT(tray_icon), "activate", G_CALLBACK(tray_activate_cb), (gpointer)app);
    g_signal_connect(G_OBJECT(tray_icon), "popup-menu", G_CALLBACK(tray_popup_menu), (gpointer)app);
}

それらを.hファイルに入れます

file.h

GObject *status_icon;

void create_status_icon(GtkWidget *app);

他の .c ファイルとメインで status_icon を使用したいのですが、valgrind は、初期化されていない値に依存する条件付きのジャンプまたは移動であると文句を言います。

main.c

GtkWidget *app;

int main(int argc, char* argv[])

gtk_init(&argc, &argv);

app = application_gui();

/* Create an tray icon */
create_status_icon(app) // <-- uninitialized

これを防ぐ方法は？

ありがとう

UPDATE valgrind 出力:
