ah I see. I just had a look at the threads.xs file.
So basically perl_clone triggers a call to the CLONE()
method of all variables ?
Thomas.
*If* they have a CLONE() method, yes. Otherwise, it just
makes a copy of the variable (including contents of arrays/hashes),
fixing up references as it goes. So if your object has a field
thats actually a ptr to a C++ object, it gets copied as a scalar.
Which may cause your DESTROY() to invoke the C++ object's
destructor twice, or reference a dead ptr the 2nd time DESTROY()
is called.
Note that a thread::shared objects don't get cloned
(tho the thread-private "proxy" wrapper does), and its DESTROY
won't get called until the last referencing thread exits.
