I think we should patch test/CMakeLists.txt to always use -Wall -Werror on *nix and the corresponding MSVC flags. It is way too easy to overlook a warning in the CI output as #1797 has shown.

People may accidentally use unsupported features such as serializing private classes reflectively (due to KT-38285) or renaming a companion object.

Some constrained systems may require the use of custom allocator like some ports using freeRTOS. So a way of redefining the allocators for _cbor_value_dup_string could be useful.

cbor_item_t *cbor_tag_item(const cbor_item_t *item)
Get the tagged item.
Return
incref the tagged item
Parameters
item[borrow]: A tag

This API does not increment the reference count so either the documentation is incorrect or the code is. The result of this is a system crash, primarily due to the change that checks the reference count:

1. GenCodec with CborInput/CborOutput from AVSystems scala-commons.
2. CBORFactory from the jackson-dataformat-cbor library that can be used with the jackson-module-scala library.

JSON-pointer is relative new compared to JSON, so it is good to have an introductory page on JSON-pointer and have references to advanced materials.
