Clone() _always_ should look like

The copy constructor is something like
Something::Something(Something const t)
{
// make sure we are an exact copy of t
}
If it is not defined by yourself, the compiler will provide one
automatically by using the copy constructors of all Something::members.
This is often exactly what is necessary, but it breaks with "naked owning
pointers", since it copies the only _pointer_ itself and does not create a
copy of the item pointed to.
(The same holds true for operator=() btw)
This necessity to manually handle copy construction and assignment (and
destruction) when using "naked owning pointers" is one of the major reasons
why we should used some kind of smart pointer (like boost::shared_pointer)
as class members instead.

Can you give details on your system (compiler, libraries etc.). > #0 0x40151530 in ostream::operator<< () from /usr/lib/libstdc++-libc6.2-2.so.3 > #1 0x81aefbf in MathDotsInset::Write (this=0x8413670, os=@0x20) ^ How did this happen ? > at math_write.C:59 > #2 0x81af897 in MathParInset::Write (this=0x8413300, os=@0xbfffcc18, > fragile=false) at math_write.C:237

Maybe your compiler ???
