scm_utime failing

[Seth Alves <alves@hungry.com>]

I have a script which makes a backup of some directories.  I've
noticed it failing, at times.  It prints messages like these:

  Error: exception
         wrong-type-argument
         (return-from-callback "scm_utime" '#{Random object})

  Error: exception
         wrong-type-argument
         (return-from-callback "scm_utime" 'Scheme48 heap overflow

  Error: exception
         wrong-type-argument
         (return-from-callback "scm_utime" '#{Weak-pointer})

  and others.

I'm using scsh 0.6.2.  I've seen this happen on a redhat 7 linux system
and on freebsd-current.

Here is enough of the script to see the problem (touch a file called 'f'):

   #!/usr/local/bin/scsh -s
   !#
   (let loop ()
     (set-file-times "f" 1024079740 1024079740)
     (loop))

It runs fine for a while, but should eventually crash.
