[Maire Reavy [:mreavy]]

Paul - Can you take a look and assess severity?

Comment 3

[Paul Adenot (:padenot)]

Probably an use-after-free on a MediaStream, but this is weird.

The only thing that has changed there recently is some refactoring to make it faster by baku (around 10 days before this report). It has only happened once, a while back, and has not happened since. Maybe something else corrupted some memory, and it happened to be on the MSG ? I don't know.

[Andrew McCreight [:mccr8]]

This hasn't happened in a while, and somebody looked at it, and couldn't figure anything out, so I'm going to close this for now.
