Re: Senora GC ?

["Ji-Yong D. Chung" <virtualcyber@erols.com>]

    Does this mean the registered location cannot be on
stack, but must be on heap that is not deleted?

    If it is on stack, it must outlast the lifetime
of the garbage collector, right?  Otherwise,
woudn't it try to delete the location (which may
not exist)?

Thanks in advance.
