You're passing a temporary regex object to the iterator, the regex object
must exist for the lifetime of the iterator (before you suggest it.... in a
future regex release, I want to make regex copying O(1) and store a copy
rather than a reference here).

I made this requirement clear in the regex_iterator docs, but apparently not
in the regex_token_iterator docs, so I'll get them updated ASAP,

Thanks,

John.
