The tokenizer caches output for common chunks, for efficiency. This cache is be invalidated when the tokenizer rules change, e.g. when a new special-case rule is introduced. That's what was causing #1061. When the cache is flushed, we free the intermediate token chunks. I *think* this is safe --- but if we start getting segfaults, this patch is to blame. The resolution would be to simply not free those bits of memory. They'll be freed when the tokenizer exits anyway.
