Thank you all for your help.

I tried adding stderr to my printf function but it still seems to be
buffered. Here is the code that I am working with:

#include <gtk/gtk.h>
#include <stdio.h>

void on_combobox1_changed (GtkComboBox *widget, gpointer user_data) {
   printf("on_combobox1_changed event");
//    int hello = GPOINTER_TO_INT(user_data);
//    printf("%d", hello);
//    GtkWidget window = GTK_WIDGET( widget );
   GdkColor color;
//    gdk_color_parse(gtk_combo_box_get_active_text(widget), &color);
   gdk_color_parse("blue", &color);
   gtk_widget_modify_bg (GTK_WIDGET (widget), GTK_STATE_NORMAL, &color);
}

void
on_window_destroy (GtkObject *object, gpointer user_data)
{
   printf("on_window_destroy event");
   gtk_main_quit ();
}

int
main (int argc, char *argv[])
{
//    GtkWidget *combobox1;
   GtkBuilder      *builder;
   GtkWidget       *window;
   GdkColor red;

   gtk_init (&argc, &argv);

   builder = gtk_builder_new ();
   gtk_builder_add_from_file (builder, "testcolor1.xml", NULL);
   window = GTK_WIDGET (gtk_builder_get_object (builder, "window"));
   gdk_color_parse ("red", &red);
   gtk_widget_modify_bg (window, GTK_STATE_NORMAL, &red);
   gtk_builder_connect_signals (builder, NULL);
//    GtkComboBox *combobox1 = GTK_COMBO_BOX (builder);
//    g_signal_connect(G_OBJECT(combobox1), "clicked", G_CALLBACK
(on_combobox1_changed), NULL);

   g_object_unref (G_OBJECT (builder));
   gtk_widget_show (window);
//    gtk_widget_modify_bg (window, GTK_STATE_NORMAL, red);

   gtk_main ();

   return 0;
}
