dynamic_cast of a reference and -fno-exceptions

[Daniel Gutson]

Hi,

  should gcc warn at least if a dynamic_cast of a reference is used when
-fno-exceptions is specified?

At least 4.8.2 doesn't complain.

If so, I can implement the fix.

Example:

struct Base
{
    virtual void f(){}
};

struct Der : Base {};

int main()
{
    Der d;
    Base& b = d;
    dynamic_cast<Der&>(b);
}


  Daniel.
