Status: RESOLVED DUPLICATE of bug 1544446

(Core :: Graphics: CanvasWebGL, defect)

Description

[Joel Maher ( :jmaher ) (UTC -8)]

I am working on getting tests running in 10.14 as we are planning to upgrade our test infrastructure.

I found 3 tests in the mochitest-errata.ini file that I needed to comment out for a crash:
[generated/test_2_conformance__rendering__rendering-stencil-large-viewport.html]
[generated/test_2_conformance2__textures__misc__generate-mipmap-with-large-base-level.html]
[generated/test_2_conformance__canvas__drawingbuffer-static-canvas-test.html]

you can see the try jobs here:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=f76caa997d7b6d7908ac0632bec21e3fbc94189f

and a log file:

The crash is on shutdown, so not at runtime, here is a clip from the log:
