does this happen without e10s activated?
Flags: needinfo?(mozillamarcia.knous)
Will try this again next week. Yesterday we had a network outage and today I don't have that machine to test.

> does this happen without e10s activated?

Yes, it definitely does with the Vista machine - the signature is a bit different when I crashed today ->

Priority: -- → P1
The only place allocating memory here is the new AudioData, so could make it fallible there as well and return an error when OOM
Flags: needinfo?(cpearce)
Sounds reasonable to me. Failiablize all the mallocs!

Marcia, can you reproduce the crash in a debug build? so we can check which part fails to allocate data?
Flags: needinfo?(mozillamarcia.knous)
likely fixed by bug 1127122
Attached file debug.txt
Here is a log when the video is running in a debug nightly build. Eventually I get an app crash dialog and the browser stops.

I don't think this needs the MemShrink tag. Looks like it's in hand anyway.

Since we have moved over to testing aurora, I have not seen this crash on the same Vista machine. Also the video used for testing has been removed from you tube, so I cannot retest with the exact same video. 

Resolving this as WFM for now, it it is seen again I can reopen it.

I got an OOM crash after over 100 hours of playing back YouTube :) Posting this up in case this stack trace helps with further bulletproofing.
