Thanks for your explanation.

I was not so used to such a temporary mismatch in the mentioned application
binary interface version from the usual software evolution.

If I adjust the symbolic link "/usr/local/lib64/libstdc++.so.6" for a moment so
that it points to a file "libstdc++.so.6.0.21", the  command like "zypper
list-updates" works again as expected.
