Message-ID: <CMM.0.92.0.1044987944.beebe@suncore.math.utah.edu> (raw)
I just tried the posted example of (sqrt long-digit-string) with
guile 1.6.3 on Sun Solaris and got similar scanner errors.
I then chopped off trailing digits and made repeated experiments.
With an input line of 256 characters, guile reports a reasonable
numeric answer. With 257 characters, it goes into a wait state.
With 258 character, it reports the scanner error.
Evidently, there is some sloppy, and unreasonably limited, buffer
handling going on here. Lisp programs should be able to read tokens
of arbitrary length (limited only by available memory); otherwise,
bignum arithmetic is infeasible.
