Jakub NerudaTip 83 of <a href="https://techhub.social/tags/TuesdayCodingTips" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TuesdayCodingTips</a> - Curious case of NLOHMANN_JSON_SERIALIZE_ENUMI recently debugged a case where code generated by NLOHMANN_JSON_SERIALIZE_ENUM failed at invariant assertions deep in the nlohmann_json library. When examined under a debugger, the data looked in line with the invariants, but there were different from what I expected.Upon expanding the macro, I found a static const array in the generated function body. This was suspicious as I knew the code is running multiple serializations in parallel and that static array was the only shared state between threads.But the C++ standard clearly states such initialization is thread-safe! Except that our project had a particular MSVC flag set - /Zc:threadSafeInit- (which disables thread-safe initialization), for good reasons I can't talk about.Takeaway - the problem isn't always in the code itself. Trust your gut feeling and dive into the compiler flags as well!<a href="https://techhub.social/tags/cpp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cpp</a> <a href="https://techhub.social/tags/programming" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#programming</a> <a href="https://techhub.social/tags/tips" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#tips</a>
