Please report any other irregularities here.
In https://hg.mozilla.org/mozilla-central/rev/4b2b6c39adf9 (bug 839641) I added a SyncFrameMetrics method CompositorParent which was overridden in the AndroidCompositorParent subclass in Fennec. The AndroidCompositorParent subclass was introduced in bug 860613 a couple of weeks ago. The refactoring in bug 861727 moved some of the stuff in CompositorParent out into a AsyncCompositionManager class, including the SyncFrameMetrics method. This means the override in AndroidCompositorParent is now on the wrong class, and therefore that code path is broken. The code path is disabled by default so it will not manifest anywhere. However, the MOZ_OVERRIDE tag on the function causes builds with gcc 4.7 and up to fail.
Glad to see MOZ_OVERRIDE catching real bugs :)
Created attachment 743837 [details] [diff] [review] Patch Still building this locally. It makes SyncFrameMetrics a non-virtual function, similar to how SetFirstPaintViewport, SetPageRect, and SyncViewportInfo work.

Sorry about breaking your patch and thanks for the fix - bug 861727 turned into rebase hell, I presume I missed this in one of the rebases.
