Thank you for your answer. This approach of implementing reference counting internally within a Span seems impractical. Because reference Counting with void* rpcz_parent_span Fails Across Bthreads: Raw pointers in LocalStorage cannot detect when the referenced Span is destroyed in another bthread. When a parent Span is deleted (after its reference count reaches zero), child bthreads still hold the same pointer value pointing to freed memory, causing use-after-free. Each Span's reference count only tracks its own operations and cannot prevent destruction when other bthreads still reference it through raw pointers. @yanglimingcn -- This is an automated message from the Apache Git Service.
