memory corruption in free leading to abort() while playing video
a memory corruption occurred in CFRelease(), which came from freetype while playing a video but I'm uncertain how this might have occurred. As I recall I was fast forwarding something in the video slidebar.
This may be related to #20936 (closed) but the traceback looks very different and it's also not clear which component it came from so I'm filing this as a separate bug.
The traceback is attached, please let me know if there's anything else I can provide
