Problem with bessel_y with negative floating point arguments

(C1) bessel_y(-0.2,3);

Error: Caught fatal error [memory may be damaged] Fast links are on: do (si::use-fast-links nil) for debugging Error signalled by CATCH. Broken at MACSYMA-TOP-LEVEL. Type :H for Help. MAXIMA>>:q (C2) build_info();

Maxima version: 5.9.0 Maxima build date: 19:10 2/9/2003 host type: i686-pc-mingw32 lisp-implementation-type: Kyoto Common Lisp lisp-implementation-version: GCL-2-5.0

Also, when the argument is a complex float, some (I'm assuming) debugging information gets printed

(D2) (C3) bessel_y(-0.2 + %i,3); az, aa = 1.019803902718557 1.0737418235E9 fn = 3.0 az, aa = 1.019803902718557 1.0737418235E9 fn = 3.0 (D3) - 3.423818579742703 %I - 2.529723678563717 (C4)
