catchExceptionByValue / exceptRethrowCopy and Fundamental types

[Yannick HOUDOT]

I agree that exception should by caught by reference and not re-thrown as a copy ... in general.
But when the exception is a fundamental types like an enum or a int... it costs less than a reference.

I was wondering if an exception could be made in a case of enum, integers, or any simple type with a size smaller than a pointer ?

Can you share some example code? This is clean:

enum E { E0 };
int f() {
    try {
        throw E0;
    } catch (E e) {
        return e;
    }
    return 1;
}

ok, my bad...
in my analyse, cppcheck didn't have access to the definition of the enum E (in your example).

all is good, sorry for the noise.
