    # Tcl Bug 1001997
    # Here, we're trying to test a case that causes a crash in
    # TclCleanupLiteralTable.  The conditions that we're trying to establish
    # are:
    # - TclCleanupLiteralTable is attempting to clean up a bytecode object in
    #   the literal table.
    # - The bytecode object in question contains the only reference to another
    #   literal.
    # - The literal in question is in the same hash bucket as the bytecode
    #   object, and immediately follows it in the chain.
    # Since newly registered literals are added at the FRONT of the bucket
    # chains, and since the bytecode object is registered before its literals,
    # this is difficult to achieve.  What we do is:
    #  (a) do a [namespace eval] of a string that's calculated to hash into
    #      the same bucket as a literal that it contains.  In this case, the
    #      script and the variable 'bugbug' land in the same bucket.
    #  (b) do a [namespace eval] of a string that contains enough literals to
    #      force TclRegisterLiteral to rebuild the global literal table.  The
    #      newly created hash buckets will contain the literals, IN REVERSE
    #      ORDER, thus putting the bytecode immediately ahead of 'bugbug' and
    #      'bug4345bug'.  The bytecode object will contain the only references
    #      to those two literals.
    #  (c) Delete the interpreter to invoke TclCleanupLiteralTable and tickle
    #      the bug.
