Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Norman Gray (normang) Assigned to: Nobody/Anonymous (nobody) Summary: Recursive library import causes StackOverflowError Initial Comment: When two modules require each other, SISC produces a StackOverflowError. Such a mutual import may or may not be a good thing to do, but it's not documented in the manual (ch 10) as being forbidden, and even if it is to be forbidden, it would probably be best to detect and forbid it explicitly. % cat m1.scm (require-library 'm2) (module m1 (m1-function) (import m2) (define (m1-function) 'm1)) % cat m2.scm (require-library 'm1) (module m2 (m2-function) (import m1) (define (m2-function) 'm2)) % sisc SISC (1.16.6) #;> (require-library 'm1) Exception in thread "Thread-2" java.lang.StackOverflowError at sisc.nativefun.NativeProcedure.apply(Unknown Source) at sisc.exprs.AppEval.eval(Unknown Source) at sisc.interpreter.Interpreter.next(Unknown Source) at sisc.exprs.AppExp.eval(Unknown Source) ... ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=379534&aid=2728484&group_id=23735 |
