From 84c5421644314a301ecb1312bbb4e1ff7e1a729d Mon Sep 17 00:00:00 2001 From: Niels Lohmann Date: Tue, 27 Oct 2026 20:31:53 +0100 Subject: [PATCH] Fix regression1 operator[](json_pointer) test under JSON_NO_THREAD_LOCAL (#5952) The test relies on a copied fifo_map restarting its timestamps. Copying a basic_json does that only on the recursive path; with JSON_NO_THREAD_LOCAL the copy is built member by member and keeps correct timestamps, so the premise was missing and the test failed (ci_test_no_thread_local, MinGW clang). Copy the object_t explicitly to create the state on every path.
