The cert-err09-cpp check is an alias, please see misc-throw-by-value-catch-by-reference for more information.

This check corresponds to the CERT C++ Coding Standard recommendation ERR09-CPP. Throw anonymous temporaries. However, all of the CERT recommendations have been removed from public view, and so their justification for the behavior of this check requires an account on their wiki to view.
