Summary: Integrating f(x) with limits after calling throws Lisp Error

Initial Comment:
/*wxMaxima 0.7.5 http://wxmaxima.sourceforge.netMaxima 5.15.0 http://maxima.sourceforge.netUsing Lisp GNU Common Lisp (GCL) GCL 2.6.8 (aka GCL)Distributed under the GNU Public License. See the file COPYING.Dedicated to the memory of William Schelter.The function bug_report() provides bug reporting information.

(%i1) integrate(f(x),x,a,b);
(%o1) integrate(f(x),x,a,b)

(%i2) reset();
(%o1) [lispdisp,linenum,%,current,tr-unique,rhs,lhs,nobjects,+labs,algdelta,_,__,context]

(%i2) integrate(f(x),x,a,b);
Maxima encountered a Lisp error: Error in MACSYMA-TOP-LEVEL [or a callee]: NIL is not of type INTEGER.Automatically continuing.To reenable the Lisp debugger set *debugger-hook* to nil.

(%i3) 

This happens if both versions 5.15 and 5.14

The reason this is important to me is that I'm writing a program which needs to call reset() a lot between calculations (so that the calculations don't have the possibility of interferring with each other).

Thanks!
