I never tried, we all use valgrind in general. It looks like it's
independent of the project, so you can try:

G_SLICE=always_malloc LD_PRELOAD=libefence.so.0.0 gst-launch-1.0 ...

This is well documented in the Efence man page. The G_SLICE addition is
to avoid using GLib optimized heap for small objects. It is not seen as
alloc/free calls by these tools otherwise.
