After installing todays updates in my Ubuntu 22.04 machines compiling with Clang fails. Standard header files are not found anymore. E.g.
evaluate.cpp:19:10: fatal error: 'algorithm' file not found
Tested with two different applications that support Clang compilation (e.g.https://github.com/official-stockfish/Stockfish ) and two different machines.

Edit: Will look at the update history later (no time now) but while updating I saw a package "cpp-12" being installed/updated. This is probably gcc-12 and maybe it mixes some header files that are also used by Clang. Just a guess...

Edit2: Meanwhile I removed cpp-12 (which also removed nvidia-dkms packages) but no luck. Clang still doesn't find standard headers.

Edit3: Installing g++-12 did it. Clang compilations works again.
