Sierra could add an extension so that there is a "scdll_Finalize" callback in the DLL extension so static objects/threads can be cleaned up outside of DLL main, and avoid loader lock issues (which is what will happen if you use threads in global objects like openssl, etc). I worked around it by using a reference counted singleton which works, but it requires a study be initialized to load the object in the first place. std::shared_ptr<GlobalObject> GlobalObject::instance() { auto sp = s_weak.lock(); if (!sp) { sp = std::shared_ptr<GlobalObject>(new GlobalObject()); s_weak = sp; } return sp; } You keep the shared_ptr in your study state and clear it on LastCallToFunction Date Time Of Last Edit: 2026-06-03 20:31:02
