I have been able to identify a regression when runing the ColdBox test suites. Once you add some object references to a struct via a `put()` operation, lucee throws a stack overflow error. You can see the full regression in the build: https://travis-ci.org/ColdBox/coldbox-platform/jobs/584141244
The offending code can be found here: https://github.com/ColdBox/coldbox-platform/blob/development/system/core/events/EventPool.cfc#L48
I have changed it to a CFML struct and an ordered struct to test and all 3 cases the exception is thrown as well. The CFC instance I was trying to store was the CFC that was actually being executed (The Test).
