Trap your errors .. and link/unlink.

splice (@{$vips{$k}{'stack'}},0,$#{$vips{$k}{'stack'}}-50) if ($#{$vip
+s{$k}{'stack'}}>50);

    Well cooked!  Oddly enough, all you need is:    splice @{$vips{$k}{'stack'}}, 0, -50; It will leave the array untouched if it is not greater than 50. 
    $ perldoc -f splice
   . . .
   If LENGTH is negative, leaves that many elements off the end of the
+ array.

    (I guess they mean "off the deleted array" -- at all events, that's how it works (and also what makes sense).  It's explained clearly here!)
