Description

[Kevin Brosnan [Ex-Mozilla]]

This bug was filed from the Socorro interface and is 
report bp-a56ce0dd-86ae-4021-83dd-cc2812140425.
=============================================================

Crash playing back mostly mp3 media. Happens on Android 4.2 and higher. Slightly more prevalent on Nexus devices though the device list is quite large and not specific to a device, oem or chipset.

I am able to reproduce this by having an email with several pages that contain mp3s and consecutively opening them till Firefox crashes.

This is on the edge of a top crash on beta #11 for beta 8. #18 in release.

I can't reproduce this, but it looks like these allocations should be fallible anyway.

Kevin, could you try this build, please:

Crashed in libmozalloc.so https://crash-stats.mozilla.com/report/index/5d2f8b05-7885-4803-8458-4dda02140430 Try the following URLs. The second broadcastify link has been triggering it for me.

Interesting. These seem to be largely streaming links.

Kevin, I'm still having some trouble reproducing this; could you be more specific about STR here?

Does it happen when you open just one of these links?
How long does it take before fennec crashes?
Do you have to open many of the links to reproduce? in different tabs or just playing then clicking back?

Thanks.

I can consistently reproduce this by playing any music from music.baidu.com -> Lock screen with passcode -> unlock screen
