It's possible the complaint is about the `list' call.  I changed
`list' to be implemented using scm_list_copy, which of course reports
itself as `list-copy' if the list is improper.  But I can't think how
an improper list could arrive there from a "(list x y)" call.

I suppose that's the killer, a port gc-ed prematurely.  Perhaps
there'd be some significance in which one it was.  port-for-each looks
pretty safe, maybe the port table has gone bad earlier.



Not sure how this would relate to the following bit you posted
before.  If this bit was taken literally it'd sound like something
evil in scm_call_1 I suppose.
