The official CVE description (https://nvd.nist.gov/vuln/detail/CVE-2018-21232) only highlights a stack consumption in "find_fixed_tags" (and this is actually fixed and is one of the included patches) but as stated in the github issue (https://github.com/skvadrik/re2c/issues/219 that is still open) there are also other recursion with the same problem and not all have been fixed by upstream. So we could say the CVE is "officially" fixed.
Tell me if I can remove the "partially" and add the CVE in the description, thanks.
