This is occurring across all platforms. The patches in Bug 1530412 undo some complex and error-prone bitfields and move some fields to LazyScriptData. The LazyScript struct should be the same size as before, but the LazyScriptData struct grows slightly in cases when it is used. My original estimates for how often the (optional) LazyScriptData is used seem to be way off.
