Memory Leak With glimagesink on OSX

Using the Mac OSX packages from the 1.15.1 release the following pipeline leaks memory:

gst-launch-1.0 testvideosrc is-live=true pattern=black ! timeoverlay ! glimagesink

On my machine it starts off using ~17MB but will continue to climb. At a certain point quitting the application will then cause the video output on the machine to freeze for many seconds, the length of which correlates to how much memory the process is currently consuming.

Please let me know if if additional logs would be helpful.
