gdk: Ensure resources registration happens once (1.14 KB, patch)
2016-04-26 08:10 UTC, Emmanuele Bassi (:ebassi) 		committed Details | Review

Description Christoph Reiter (lazka) 2016-04-26 07:31:25 UTC 
Cause https://git.gnome.org/browse/gtk+/commit/?id=55537cccbd8129ed9fd3d00e8af07c05719516ac

-------

#include <gtk/gtk.h>

/* gcc -Wall `pkg-config --cflags --libs gtk+-3.0` a.c */

int main(int argc, char *argv[]) {
  GtkWidget *window;

  gdk_init (&argc, &argv);
  gtk_init (&argc, &argv);

  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_widget_show_all (window);

  gtk_main();

  return 0;
}

-----

Before trying the above I recommend "sudo swapoff -a", or your machine will swap immediately.

The cause is calling gdk_init() before gtk_init() and somehow results in gresource.c:lazy_register_resources() looping forever.
