| tyhicks | mozjs contains a copy of the SpiderMonkey JavaScript engine |
| chrisccoulson | This is not fixed in mozjs52, but it's unclear whether it is unaffected or just ignored as https://bugzilla.mozilla.org/show_bug.cgi?id=1392026 is still private and I can't find a changeset referencing it) |
