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