1117412 - Memory leak and crashes with videos on a carousel rotation

Status: RESOLVED INCOMPLETE

(Core :: JavaScript Engine: JIT, defect)

Description

[masterx244]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0
Build ID: 20141125180439

Steps to reproduce:

Pinning robertsspaceindustries.com as a app-tab on a clean install of firefox 34 on Windows OS (VM was Windows 8 but i got similar behavior on WInods7 Professional)


Actual results:

after some hours of unattended running inside a Virtual Machine with 8GB of Ram (to simulate long running firefox-session with that tab pinned) Firefox crashed 
(https://crash-stats.mozilla.com/report/index/de9bef48-fe35-4f71-b685-f459f2150103).

Got the suspiction that it is related to video decoder by adblocking the mp4 files on the website and haven't gotten the weird behavior 


Expected results:

Firefox should not have crashed

(I've not tried to reproduce, but the VM-based steps make me expect that this is fairly consistent)

I can't reproduce this on OS X. Kannan, can you try this on Windows with Firefox 34?

Ok, trying to repro this now.

I tried to replicate this for a while with firefox 34, with no luck, before I realized I have to leave it running for a while, and probably longer than a few hours since my box has more memory.

masterx, can you still reproduce on win7 with current nightly build?
I was unable to reproduce
