Attachment: Debug Crash report OSX 10.6 [@ SkDashPathEffect::SkDashPathEffect(float const*, int, float)

Related but OSX 10.6 only?

2. Debug Nightly/41 Crash 

I can't do much here since Nightly doesn't display on my OSX 10.6 machines though it appears to load content.

Comment 2

[Andrew McCreight [:mccr8]]

Milan, is there somebody who can look at this?  Thanks.

Comment 3

[Milan Sreckovic [:milan] (needinfo for best results)]

[Tracking Requested - why for this release]: We default to Skia canvas as of 40.  This crash is there with Skia canvas only.  We should track this and make sure we fix or roll back the preference change.

Comment 4

[Markus Stange [:mstange]]

In 7508f335-408f-4579-9959-6aa952150517 the crash is happening in a worker thread, and bug 857895 (which made us use worker threads) was backed out for crashes like these. See also bug 1165799 and bug 1165710.

Comment 5

[Ritu Kothari (:ritu) (Inactive, please n-i to RyanVM, jcristau, or pascal)]

This is a sec-high and reproducible bug so adding a tracking flag for FF40 and FF41.

Comment 6

[Milan Sreckovic [:milan] (needinfo for best results)]

Comment 4 is suggesting this is "fixed" with the backout of bug 857895.  Bob, can you still reproduce?  I can't on 10.9.5.

Comment 7

[Bob Clary [:bc]]

I can't reproduce in automation on osx/rhel/windows. -> fixed by backout.

Comment 8

[:dmajor]

Is fx40 really affected? I don't think 857895 ever landed there.

Comment 9

[Bob Clary [:bc]]

fwiw, I don't recall seeing this on anything but 41 and tested 39,40 and 41 when I checked this.

Comment 10

[Matt Wobensmith [:mwobensmith][:matt:]]

Confirmed crash on Fx41 debug, 2015-05-16. 
Verified fixed on Fx41 debug, 2015-05-28.
