Bug Description

Binary package hint: maxima

Running the command

factor(x^4-4*x^2+1), modulus=3;

in maxima 5.17.1-1ubuntu1 causes the following error

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]

Running it a second time can cause a segfault.

This occurs on both i686 and x86-64.

Strangely enough, Debian testing package 5.17.1-1 does not exhibit the same problem.
