This impacts version 1.2.0 as well as earlier versions of HL for iOS.
Specifically the leaks I am talking about are in the LEAK-AS-OF-MAY19-2016 folder:
All I did was run the hyperloop-examples program (from master) and click on auto layout and then hit the back arrow and then hit View Animation. As you can see each time I invoke hyperloop objects I got 51 new leaks between those two actions. I got 19 leaks upon initialization of the app.
I think this is the same leak behavior I observed back in February.
I had to custom compile a version of titanium since master is currently broken. see https://jira.appcelerator.org/browse/AC-3640
I built appcelerator/titanium_mobile master at has aafdb83
I mention this just to document it, but I don't think this is an important detail.
