When both clang and gcc are installed, in my case, clang(14) defaults to c++14, and gcc(12.2) defaults to c++17.
And the default compiler is gcc.
You may get unexplained compiler errors in your scan-build output.
This is because scan-build does not automatically add an explicit `-std=c++17` to the clang compiler command-line it uses internally.
I ran into this problem with a cmake based project. cmake omits unnecessary compiler flags depending on your compiler version. You can of course add the `-std=...` option explicitly, but that does not make the project files any prettier.
