Memory leak with very simple test
I got the following memory leak while testing with these simple commands:
G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind --leak-check=full --leak-resolution=high --num-callers=20 --trace-children=yes --suppressions=/home/nvidia/massif/gst.supp --suppressions=/home/nvidia/massif/glib.supp gstd -D

- Jetson TX2 (JetPack 3.2.1)
