541753 - Extreme memory leak on pages with HTML 5 Audio objects

Status: RESOLVED DUPLICATE of bug 503989

(Core :: Audio/Video, defect)

Description

[Joseph Huckaby]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6

Pages that contain HTML 5 Audio objects consume memory, but the memory is never released, even if the window is closed.  On my test page, Firefox eats another 15 MB or so for every single refresh.


Reproducible: Always

Steps to Reproduce:
1. Go to http://bowser.macminicolo.net/~jhuckaby/bugs/firefox-ogg1/leak.html
2. View Firefox's memory usage, either using an external utility, or "about:memory"
3. Refresh the page, and then examine Firefox's memory usage again.
Actual Results:  
Firefox's memory usage grows by about 15 MB for every page refresh.  The memory is never released.

Expected Results:  
Firefox's memory should not continuously grow in this fashion.  The memory used by the HTML 5 Audio objects should be released when the page is closed.
