What's wrong with this code? When I try to compile it using ocamlc
3.06 the compiler hangs on Win32 and on Debian Linux as well. The
ocaml interpreter does the same.
It works when I changed Oo.copy self to {<>} or simply self.
class virtual duplicatable =
object (_ : 'a)
method virtual dup : 'a
end
class test =
object (self)
inherit duplicatable
method dup = Oo.copy self
end

Looks like a bug.
But the CVS version chomps it happily, so this bug is already fixed
for the next release.
Anyway, it makes more sense to use {< >} to get a copy of self (the
meaning is just the same as Oo.copy self).
