=============================================================

these content crashes on osx 10.12 upwards started regressing in volume during the 62 nightly cycle after 62.0a1 build 20180602100108 - presumably due to bug 1466066.

some crash comments seem to suggest that firefox is crashing repeatedly during video playback for affected users.

[Alex Chronopoulos [:achronop]]

I am looking at it, thanks.

Comment 2

[Mike Taylor [:miketaylr]]

I don't see any crashes in 63, which is interesting.

Comment 3

[Julien Cristau [:jcristau]]

Looks like they're nightly/aurora only, hitting the assert(r == 0 && "Deadlock"); in media/libcubeb/src/cubeb_utils_unix.h.  I guess that'd show up under a different form with asserts disabled.

Comment 4

[[:philipp]]

bug 1471164 should have fixed the issue on 63. given that only aurora is affected, should we uplift the cubeb fix or is 62 already in a good state?

Comment 5

[Alex Chronopoulos [:achronop]]

62 is affected. We need to uplift if we want the fix there.

Comment 6

[Jan-Ivar Bruaroey [:jib] (needinfo? me)]

Fixed by bug 1471164.

[Tracking Requested - why for this release]: crashes.

Comment 7

[Jan-Ivar Bruaroey [:jib] (needinfo? me)]

Ah, tracked in bug 1471164.
