limit ((cosh(sqrt(x+1))-cosh(sqrt(x)))^(1/sqrt(x)),x,inf ); => Maxima encountered a Lisp error: overflow during multiplication of large numbers

The immediate cause is that Maxima wants to calculate (POWER '4 '-7431782400)

but I didn't investigate what chain of events led to that.

Example above is with Clisp. CMUCL gives a similar error while SBCL and ECL simply grind away indefinitely.
