sds_add_event_listener / sds_remove_event_listener run on the foreign caller thread and allocate Nim memory ($eventName, the listener registry Table+seq), but unlike the ctor/dtor they never called initializeLibrary. A foreign host (Go) migrates goroutines across OS threads, so the thread running add_event_listener may not be the one that ran a prior entry point; without setupForeignThreadGc its per-thread allocator region is uninitialised and the first Nim allocation faults in the allocator.
