Category: Lisp Core - Polynomials Group: None >Status: Closed Resolution: Fixed Priority: 5 Private: No Submitted By: Stavros Macrakis (macrakis) Assigned to: Nobody/Anonymous (nobody) Summary: factor(r^2-3*r+3,a^3+1) fatal error Initial Comment: factor(r^2-3*r+3,a^3+1) Error: Caught fatal error [memory may be damaged] Error signalled by PFACTORALG1. (should be irreducible) This happens regardless of the setting of GCD. Note that various close-by cases work just fine: ..., a^2+3 (factors) ..., a^2+2 (irreducible) ..., a^2+1 (irreducible) ..., a^3+3 (irreducible) ..., a^4+1 (irreducible) ..., a^4+3 (factors) ..., a^6+3 (factors) Maxima 5.9.0 gcl 2.5.0 mingw32 Windows 2000 Athlon ---------------------------------------------------------------------- >Comment By: SourceForge Robot (sf-robot) Date: 2007-08-18 19:20 Message: Logged In: YES user_id=1312539 Originator: NO This Tracker item was closed automatically by the system.

This should not cause a fatal error, but an error message. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=792862&group_id=4933 |
