from the memoization part of the file. (copy_tree): New static function (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic structures are detected now and will lead to an exception instead of forcing guile to run in an endless loop, using up all the system's memory. Second, arrays in the cdr of an improper list are now copied. See the new test cases in eval.test. * test-suite/tests/eval.test: Added tests which reflect the recent fixes to copy-tree.
