From 5999d3f936460a4549c8e414b8ab1e38cab3cf14 Mon Sep 17 00:00:00 2001 From: Bhagirath Mehta Date: Thu, 24 Sep 2026 02:58:36 -0500 Subject: [PATCH 1/2] Keep Objective-C configuration copies independent and owned Move the wrapped configuration from file scope to a per-instance owning pointer, preventing later copies from redirecting earlier wrappers and leaking prior allocations.
