Hitting this DCHECK on clean branch sync'ed to 3a2e44ccf674a52170c9b914a290daa1f61f570b (tip of tree from april 17).

When I sync to current tip, the repro is gone. So perhaps its fixed? Thought I'd mention in case its just harder to repro now.

Steps:
1. Build with dcheck enabled
2. Play youtube video (https://www.youtube.com/watch?v=kqnvrjgyEMc)
3. While playing, control+C your command line

Maybe this CL fixed it (guessing by description)?
