[Chicken-users] segfault bug in string->number

[Robin Lee Powell]

Given the following code (with giant strings snipped):

- -------------------------------

(use srfi-1)
(use srfi-13)

(define bigstring SNIP
(define bigstring2 SNIP

(write (string-length bigstring))
(display "\n")
(write (string->number bigstring))
(display "\n")
(write (string-length bigstring2))
(display "\n")
(write (string->number bigstring2))
(display "\n")

- -------------------------------

The strings most certainly do not encode numbers, and that *should*
be obvious from the first few characters, which are "le i mi cu nu
do la se lo lu li'u".

The following output occurs:

address@hidden> csc -O2 -d0 /tmp/stn.scm ; /tmp/stn
4107
#f
5065
zsh: segmentation fault  /tmp/stn

I'm not going to try to patch it, because I *loathe* C.  In fact,
I'm using Scheme largely *because* I loathe C (I'm replacing bits of
C in the project I'm working on with it).
