Followup-For: Bug #896017
This bug is live again.
Tests of xtensor-blas report:
-- Check for working CXX compiler: /usr/bin/clang++
-- Check for working CXX compiler: /usr/bin/clang++ - broken
CMake Error at /usr/share/cmake-3.28/Modules/CMakeTestCXXCompiler.cmake:60
(message):
The C++ compiler
"/usr/bin/clang++"
is not able to compile a simple test program.
It fails with the following output:

The test passes if libstdc++-14-dev is installed. Does it mean clang
has been misbuilt against stdc++-14? Or should the stdc++
dependencies of the clang package be updated?
