Mmm, I was wondering about that one.

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?
