Re: [cdt-dev] Codan warning "Catch uses reference to exception"
|
When I did use exceptions in a previous life, I did catch by reference. I'm not sure how exceptions get implemented, but it seemed catching by value was a bad idea since it would theoretically mean always calling the copy constructor on the catch, which could lead to more problems.

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.
