Status: RESOLVED WORKSFORME

(Core :: Audio/Video: cubeb, defect, P3)

Description

[Matthew Gregan [:kinetik]]

This bug was filed from the Socorro interface and is 
report bp-248ec65a-9d44-4ca9-98dc-a39382160423.
=============================================================

Several crashes on different Android versions and hardware with this signature.

Also one with a slightly different signature (and an old Firefox) which is likely related: https://crash-stats.mozilla.com/report/index/2c3428e3-c549-4b08-9d64-17dc82160423

Looks like cubeb_stream_get_position is called with a freed stream (or the stream references a freed context in stm->context).  Not sure why this would only show up on Android, though.

Matthew - Is this something you can take a look at soon?

Comment 2

[Matthew Gregan [:kinetik]]

Probably not, I don't have anything to go on to investigate this and the rate of crashes is pretty low so it's difficult to justify spending time on this.

Looking at crashes in 2016, there are 4 with the [@ @0x0 | cubeb_stream_get_position ] signature, all on version 32 or earlier.

For [@ cubeb_stream_get_position ], there are 98 so far in 2016, 61 of which are this bug on Android, the rest are in very old Firefox builds on other platforms.

Moving to p3 because no activity for at least 1 year(s).

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.
