#1595 plot2d can't plot a sinc function

[Anonymous]

When I enter that command,
wxplot2d([sin(x)/x], [x,-20,20]);

I obtain that:
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.

If I do it whitout wxmaxima:
(%i4) plot2d([sin(x)/x],[x,-20,20]);
Universal error handler called recursively (:ERROR NIL
CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER
""
"Couldn't protect")

Automatically continuing.

we've fixed many bugs since 5.13.0; try installing Maxima 5.17.0. The plot works with

(%i1) build_info();
Maxima version: 5.17.0
Maxima build date: 19:8 12/4/2008
