From 2acd6dc5362b559539ecbe6efb3a85db47d34d2d Mon Sep 17 00:00:00 2001 From: Giuseppe Scrivano Date: Wed, 14 Jan 2026 09:17:41 +0000 Subject: [PATCH 1/5] source: fix mapStringObject clone to copy len and keys The emit_clone_body() method for MapStringObjectType was generating incomplete clone functions that only copied the values array but forgot to copy the len field and the keys array. This caused cloned structures to have len=0 and NULL keys, resulting in data loss when serializing and potential memory issues. Add a test that verifies cloning of mapStringObject types (netDevices) works correctly, including proper copying of len, keys, and values.
