Status: RESOLVED DUPLICATE of bug 1384701

(Core :: CSS Parsing and Computation, defect)

Description

[Xidorn Quan [:xidorn] UTC+11]

See https://treeherder.mozilla.org/#/jobs?repo=try&revision=b1f9504fbc383472969fd12d06f3017d635c0bfe&selectedJob=121303700 and c2 c3  follow that selected task.

It happens on Linux debug build only. It doesn't seem to happen on Mac, neither the release build.

The stack doesn't look very useful, but it is:

Looking at several tests triggering this crash, I couldn't figure out any common pattern of it :/

Comment 2

[J. Ryan Stinnett [:jryans] (Use needinfo, replies may be slow)]

Sounds like the same issue as bug 1384701 I think?  Seems like the same Cairo assertion appears here too.

Yeah, sounds like that one. It seems all of the crashes happen at the last test in each directory.
