I've checked with valgrind and there is no leak (besides small one-time
allocs), definitely nothing that grows:

I have this in my bashrc:
alias vg_memcheck='G_SLICE=always-malloc G_DEBUG=gc-friendly
GLIBCPP_FORCE_NEW=1 GLIBCXX_FORCE_NEW=1 valgrind --tool=memcheck
--trace-children=yes --num-callers=20 --read-var-info=yes
--leak-check=full --leak-resolution=high --track-origins=yes'

and then run

vg_memcheck gst-launch-1.0 audiotestsrc num-buffers=100 ! level
post-messages=true interval=30000 ! fakesink
