We're using the Gtk3::WebKit Perl bindings of WebKitGTK+ in our web application's test suite and since the upgrade to 2.4.9 from 2.4.8 (openSUSE packages) we get reproducible segfaults in pretty much all tests that use WebKitGTK+. The stack traces all look like this: #0 0x00007fffdcc6f932 in WebKit::DOMObjectCache::put(void*, void*) () at /usr/lib64/libwebkitgtk-3.0.so.0 #1 0x00007fffdcd1c147 in webkit_dom_xpath_result_constructor(unsigned long, unsigned int, _GObjectConstructParam*) () at /usr/lib64/libwebkitgtk-3.0.so.0 #2 0x00007fffe25a9bf9 in g_object_new_internal (n_params=0, params=0x0, class=0x1cb7ba80) at gobject.c:1692 #3 0x00007fffe25a9bf9 in g_object_new_internal (class=class@entry=0x1cb7ba80, params=params@entry=0x0, n_params=n_params@entry=0) at gobject.c:1772 #4 0x00007fffe25ab5e1 in g_object_newv (object_type=object_type@entry=391362448, n_parameters=n_parameters@entry=0, parameters=parameters@entry=0x0) at gobject.c:1921 #5 0x00007fffe280917e in XS_Glib__Object_new (my_perl=<optimized out>, cv=0x15d9e548) at GObject.xs:1379 #6 0x00000000004b590b in Perl_pp_entersub (my_perl=0x7a8010) at pp_hot.c:2794 #7 0x00000000004ae406 in Perl_runops_standard (my_perl=0x7a8010) at run.c:42 #8 0x0000000000440c8d in perl_run (oldscope=<optimized out>, my_perl=<optimized out>) at perl.c:2451 #9 0x0000000000440c8d in perl_run (my_perl=0x7a8010) at perl.c:2372 #10 0x000000000041ee23 in main (argc=3, argv=0x7fffffffd7a8, env=0x7fffffffd7c8) at perlmain.c:114 Please tell me, how I can help solve this.
