  20 # Test for %fast-slot-ref, which was previously implemented such that
  21 # an out-of-range slot index could escape being properly detected, and
  22 # could then cause a segmentation fault.
  23 #
  24 # Prior to the change in this commit to goops.c, the following
  25 # sequence reliably causes a segmentation fault on my GNU/Linux when
  26 # executing the (%fast-slot-ref i 3) line.  For reasons as yet
  27 # unknown, it does not cause a segmentation fault if the same code is
  28 # loaded as a script; that is why we run it here using "guile -q <<EOF".
