(In reply to Gerald Pfeifer from comment #14)
There's something in the ports gccs that makes them all link automatically to
/usr/local/lib/gcc10/libstdc++.so.6:

% for i in 8 9 10 11; do g++$i bug22143.cpp -o bug221423-gcc$i; done
% for i in 8 9 10 11; do ldd ./bug221423-gcc$i; done
./bug221423-gcc8:
        libstdc++.so.6 => /usr/local/lib/gcc10/libstdc++.so.6 (0x821663000)

I don't have to pass any rpath options, something implicitly stuffs in the
gcc10 libdstdc++.so.

And none of the executables crash here... FreeBSD 14-CURRENT as of ~2022-03-31.
