pnangunoori@, please do not WontFix Out-of-Memory issues unless you are the owner of the target code (//media in this particular case).

Matt, this is a top crasher for that particular fuzzer. It happens in 98+% of runs together with  issue 767416 .
@mmoroz -- Thank you very much for the update. Will follow as mentioned by you, going further.

Like  bug 770061 , this is an ASAN oom, so we should check if there are sane limits to be applied in this case.
