That doesn't seem possible. You must be doing something else that
breaks things. A strong reference is a strong reference, an object
doesn't get deallocated if it's still held. Either you have files where
ARC is still turned of (via the -fno-arc option or whatever it is
called) and are assuming it isn't, or it is an unowned
(unsafe-unretained? Whatever it was called in ObjC) or weak reference.
You also mention you're using C++. If you are passing pointers through
C or C++ code (as void* for instance), then you might be doing something
wrong there. Make sure you're properly using NSBridgingRetain() etc. (or
the equivalent typecasts) and not mixing them up. That could cause ARC
to think it owns another reference to an object and release it again.
