Thanks!

I'll check if I can teach the docs python script in the build-docs-test job to fail on segfault, that would prevent this issue in the future. So there may be some test commits on this branch.

Our doxypress config has "clang-parsing": false. Seems we are using the broken legacy doxygen lex parser that does not really understand modern C++. Is that on purpose?

[salkinium]

Is that on purpose?

Probably not, I think we took the default and just changed what was needed. If it works without having clang installed, then we can change it.

"clang-parsing": true segfaults for me 🙀
Let's not mess with it right now ...

[salkinium]

Failing properly now: https://github.com/modm-io/modm/runs/4681342161?check_suite_focus=true
And not failing with the fix.

When you have time tomorrow @rleh, you can copy the develop folder to 2021q4 release to archive it.

Already on my to-do list :)
Done ✅
