Notes for breathe - reproducible builds result

Version annotated: 4.2.0-3
Identified issues:
Identifier: randomness_in_documentation_generated_by_sphinx
URL https://wiki.debian.org/ReproducibleBuilds/SphinxIssues
Description Sphinx might output references to memory addresses and generate a json index file
with entries in random order or with non-deterministic values (eg. searchindex.js).
See https://bugs.debian.org/822197 for memory address issue
.
searchindex.js needs sort_keys=True (jsonimpl.py) but the key values vary too.
