This can be done by adding a clone() virtual function to boost::exception.

C++0x has virtual constructors?
Cloning can be supported non-intrusively, without virtual constructors or virtual clone() functions. You can have a look at the Optional Polymorphic Value object with Small Object optimization Library in the vault: *http://tinyurl.com/2og6st* The thread discussing it is: http://archives.free.net.ph/thread/20071102.211935.ab0db275.en.html The only requirement you need is that all your concrete classes derive from a know base class, and you get cloning and the small object optimization for free.
