            Status: UNCONFIRMED

Run something like :
valgrind --tool=memcheck --leak-check=yes  --leak-resolution=high
--num-callers=30 gst-launch-0.8 filesrc location="Next-Sun, Linear PCM.au" !
auparse ....

You will get :

since tempcaps are not freed in the chain function , here's the patch for it :
