Comment 5 for bug 417433

I confirm this bug on both i386 and amd64 architectures.

Ubuntu 9.10's maxima also fails to factor *any* number:

----------

Maxima 5.17.1 http://maxima.sourceforge.net

The function bug_report() provides bug reporting information.
(%i1) factor(4);
Universal error handler called recursively (:ERROR NIL
                                                  CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER
                                                  ""
                                                  "Couldn't protect")
Universal error handler called recursively (:ERROR NIL
                                            CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER
                                            "" "Couldn't protect")
Maxima encountered a Lisp error:

 Error in CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER [or a callee]: Caught fatal error [memory may be damaged]

Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.

Switching to Debian's maxima packages (cf. f0ma's comment) solves the issue:
