Unconditional sv_mortalcopy sounds like the thing to do then, but a
comment would help. And if this isn't a Perl bug, I would like to
know what is.
BTW, shouldn't we be making some attempt to drop the result of the
sv_mortalcopy? Or is it just assumed that it will be garbage-collected
before the memory leak gets too bad?
