Hi, I am using partial continuations to resume a computation when an external system returns with an answer. I am using (call-with-prompt ...) and (abort-to-prompt) When I resume the continuation in another thread, all works perfectly UNLESS the continued execution throws and exception. Then guile exits with a core dump. By contrast if I resume the continuation in the same thread and then throw and exception all works as expected. Is this a known issue? All assistance welcomed. Thanks Brent
