Apparently a TI regression: I saw a couple of these on Jaegermonkey, and this instance is from the merge to mozilla-central.

WebGL mochitest: starting page conformance/oes-texture-float.html

WebGL test error: test page failure: conformance/oes-texture-float.html and for a couple of recent JM ones, suspiciously on the same build, though the third time I retriggered on that build it passed.
Oh, this. This is an actual bug in our code. Somehow it hadn't been causing trouble until now. Test patch coming as I don't have time to fix the actual bug now and it doesn't matter hugely.
...and it does make sense that it would be triggered by a JS engine change. See the discussion in bug 630672

This test is valid, but flaky as it relies on GC happening at a particular time. A recent JS engine change making it actually happen caused it to actually catch a bug we've always had in the OES_texture_float impl, see the discussion on bug 630672, and I don't have time to fix that now.

disable the uniqueObjectTest

Personally, I'd prefer if you included the explanation of the problem inline.

This intermittent orange is really fixed by this patch. But we're still ignoring this test on linux as I first noticed it there and did improper analysis. This patch un-ignores this test.
