sorting lists of lists

[Christoph Groth]

Hello,

I think I've found a bug in Guile 1.6.0: When sorting lists of lists
with `sort!' some list items are lost.  This is how I can reproduce
the problem:

~$ guile
guile> (define l '((4) (2) (5) (1)))
guile> (sort! l (lambda (a b) (< (car a) (car b))))
((1) (2) (4) (5))
guile> l
((2) (4) (5))

Some information about my system:

I've compiled guile without any special options to `configure'.  The
only deviation from a standard installation procedure is that I've
used `stow'.
