[cdt-dev] Codan warning "Catch uses reference to exception"

[Andrew Gvozdev <angvoz.dev@xxxxxxxxx>]

Elena,

Why do you want us to avoid catching exceptions by reference? Shouldn't it be the other way around? Catching by reference is recommended by C++ experts, for example Herb Sutter/Andrei Alexandresscu "C++ Coding Standards", Rule 73 "Throw by value, catch by reference". For one thing, this avoids copying and potentially slicing the exception.
