Very impressive (and very ugly, but messing with compiler internals is 
like that).

I looked into GCC's language support library, but it seems that GCC 
doesn't store the copy constructor of the thrown object anywhere - 
neither in the exception header, nor in the type info. This is very 
unfortunate, since it means that a similar implementation is not 
possible for GCC.
