Crash when emit generated signals




Hi,

We use an old version of glib(2.30) to implement signals and call methods over dbus. After repeated calls(~200-300), we I have a crash inside g_slice_alloc when calling the g_dbus_connection_emit_signal routine(from generated code).

  g_dbus_connection_emit_signal (connection,
    NULL, g_dbus_interface_skeleton_get_object_path (G_DBUS_INTERFACE_SKELETON (skeleton)), "com.Multimedia.Playback", "AudioStreamChange",
    g_variant_new ("(suu)",
                   arg_uuid,
                   arg_stream_id,
                   arg_num_streams), NULL);

Here is my trace:

stack_trace:/lib/libc.so.6(__default_sa_restorer_v2+0) [0x368d6810]
stack_trace:/usr/lib/libglib-2.0.so.0(g_slice_alloc+0x140) [0x36c614d4]

How to prevent this ?

Thank you,
