This bug was filed from the Socorro interface and is report bp-67a53e0a-fe10-46ed-bbd3-251262160720. ============================================================= I can repro this on my macbook pro when scrolling twitter.
https://hg.mozilla.org/integration/mozilla-inbound/annotate/aac8ff1024c5/dom/media/MediaDecoderStateMachine.cpp#l445 It looks like mMediaSink is null. But MDSM never sets it to null. How reproducible is the crash?
Three times in a couple minutes, I'd say it's pretty reproducible.
Can't repro it on my Mac. Which twitter page were you browsing?
stack frame: "rax": "0x0000000000000000", It looks like the pointer to the virtual table is null. This is either a UAF or memory corruption.
Any twitter page that has video in tweets reproduces for me.
Paul - can you give a specific example please? Jean-Yves - can you repro this issue?
I can't really, I'm just scrolling my timeline (twitter.com) when logged in, it crashes often. Maybe scrolling a twitter page where there are a lot of videos will help. For example, https://twitter.com/franceinfo.
Hi Paul, Since you are able to repro this issue, can you attach a debugger and confirm if comment 4 is true?
I can't repro anymore, sorry. I'll reopen if I have more info or if I can repro.
