Reproducing a session at the gambit REPL that led to a segmentation fault:

$ uname -srmp
Darwin 14.5.0 x86_64 i386

$ gsc
Gambit v4.8.4

> (define xs '(1 2 3))
> (let* ((x (car xs)) (xs (cdr xs)) (y (car (xs))) (xs (cdr xs)) (z (car
xs))) (+ x y z))
*** ERROR IN (console)@2.43 -- Operator is not a PROCEDURE
((2 3))

1> xs
(2 3)

1> (define xs '(1 2 3))
*** WARNING -- defining global variable: xs
[1]    11502 segmentation fault  gsc

Also wondering why the `xs` in the `let*` bindings is referring to the
global `xs`.

Thanks,

--Vijay
