Dear Maintainer,

With clang++ versions 3.8, 4.0, and 5.0, the following occurs:

    rharwood@seton:/tmp$ export LC_ALL=en_US.utf8
    rharwood@seton:/tmp$ echo "int main() { return 0; }" > test.c++
    rharwood@seton:/tmp$ /usr/bin/clang++ -v test.c++
    clang version 4.0.1-10 (tags/RELEASE_401/final)

if at all, it's a clang issue not finding something

Hello

Are you sure you have libstdc++ installed?

Thanks

Yes, libstd++ is installed.

I get the same error running xtensor tests using clang

clang Depends: clang13 Depends: libstdc++-11-dev

libstdc++-11-dev installs libstd++ as
/usr/lib/gcc/x86_64-linux-gnu/11/libstdc++.so

Is it bug in libstdc++-11-dev?
