  "message": "gh-142349: Fix refcount corruption in lazy import specialization (#144733)\n\nRemove spurious Py_DECREF on borrowed ref in LOAD_GLOBAL specialization\n\n_PyDict_LookupIndexAndValue() returns a borrowed reference via\n_Py_dict_lookup(), but specialize_load_global_lock_held() called\nPy_DECREF(value) on it when bailing out for lazy imports. Each time\nthe adaptive counter fired while a lazy import was still in globals,\nthis stole one reference from the dict\u0027s object. With 8+ threads\nracing through LOAD_GLOBAL during concurrent lazy import resolution,\nenough triggers accumulated to drive the refcount to zero while the\ndict and other threads still referenced the object, causing\nuse-after-free.",
