Is this sort of stuff still swapped into your brain, jld? Or should I redirect?

Looks good, and thanks for adding that function comment.

Aside: if there's a meta-bug for improving our test frameworks to make it easier to write automated regression tests for things like this, it'd be worth cross-referencing this bug.

It gets tricky, since our mochitests inherit the add-on shims. I will file a bug about seeing if we can start turning that off test by test. Thanks for the idea.

Comment 11

[Mike Conley (:mconley) (:⚙️)]

Actually, come to think of it, a test that exercises the image saving case should have caught this, since the unsafe CPOW access occurred asynchronously inside internalSave.

I've filed bug 1244260 to get a test for this written.

Is this still an m8 blocker?  Should this uplift to 46? Thanks.

Comment 18

[Mike Conley (:mconley) (:⚙️)]

I think we're still okay here - what broke this was CPOW outlawing, which landed in bug 1233497 in 47. 46 shouldn't be affected.

Comment 19

[Liz Henry (:lizzard) (relman/hg->git project)]

OK, great.

I managed to reproduce this bug on an affected build, i.e. 47.a1 (2016-01-27) using Windows 10 x64.
This bug is confirmed fixed on 47.0b.3.
