integration error

Maxima version: 5.17.1
Maxima build date: 14:9 7/13/2009
host type: i686-pc-linux-gnu
lisp-implementation-type: GNU Common Lisp (GCL)
lisp-implementation-version: GCL 2.6.7

On Ubuntu 9.10 when trying to integrate I get the following:

(%i1) integrate(1/(x^3+1),x);
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.

It is strange, since on the previous version such error was not present. I am sure it is related to GCL, since with the same version on newly compiled FreeBSD maxima things goe the way they should:

(%i1) integrate(1/(x^3+1),x);
2 x - 1
2 atan(-------)
log(x - x + 1) sqrt(3) log(x + 1)
(%o1) - --------------- + ------------- + ----------
6 sqrt(3) 3

html garbles the text!

(%i2) build_info();

The difference is in the LISP!
