+ # 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.
