Summary: Bind stack overflow  for factor 7th degree

Initial Comment:
(%i1) 156*x^7+4808*x^6-182041*x^5-1266489*x^4+43104271*x^3
+29839285*x^2-2542327662*x+7826952672$

(%i2) factor(%);
Maxima encountered a Lisp error: Error in MACSYMA-TOP-LEVEL [or a callee]: Bind stack overflow.

The factors are all linear:

(%i3) berlefact : false;
(%o3) false
(%i4) factor(%i1);
(%o4) (x-16)*(x+14)*(x+49)*(2*x-11)*(2*x+21)*(3*x-49)*(13*x-63)

Another manifestation of the same bug is
    factor(taylor(sin(x),x,%pi/4,20);

Notice also that error message "Bind stack overflow" is (a) GCL specific
and (b) misleading.  Other lisps (clisp, sbcl, cmucl) complain that
"NIL is not of numeric type".
