I notice the working case links to __ZN17IOPolledInterface10metaClassE. I should be able to track that down by comparing differences between the projects. Sorry to reply to myself, but I want to clarify now that I solved it. It turns out the two things that are linked to are IOPolledInterface::metaClass and IOPolledInterface::gMetaClass. I didn't spot the difference in the mangled names. The former is not exported, as far as I can see, but it is not used if I only subclass IOPolledInterface. It gets used if I try to do an OSDynamicCast to IOPolledInterface. This email sent to site_archiver@lists.apple.com
