Yep, that was a bug in dimensions->uniform-array, which didn't handle
an omitted 'fill' parameter correctly.  The result was that not array
created with make-uniform-array was initialized.

Thanks for spotting this!

But note that make-uniform-array is deprecated in 1.7 and the
imminent 1.8; use make-typed-array instead:

   guile> (make-typed-array 's8 0 10)
   #s8(0 0 0 0 0 0 0 0 0 0)
