I see. The problem is in CFGetTypeID() where the pointer is accessed in an unsafe way (as you noted yourself in the code). I haven't given in much thought yet, though...

The CF_IS_OBJC() macro will correctly identify small objects. The function objc_getClass() will return a valid ObjC class that isn't toll-free bridged and so CF_IS_OBJC() should return true. This should work.

Hi,
for toll-free bridging in CoreBase, I need a way to detect whether the incoming pointer is a small object encoded in a pointer and act accordingly (treat it as an ObjC object and avoid reading it).
What is the correct approach?
Thanks!
