--- Comment #1 from Philip Hazel <ph10@???> ---
In principle, I think you are right. However, PCRE1 is in "fix only serious
bugs" mode, and I do not think this comes into that category. In PCRE2, the
minimum length field is 16-bits, and there is checking for overflow while it is
being computed. In PCRE1 the field is actually 32-bits wide. You would have to
work hard to craft a pattern that had a minimum matching length that would
overflow 32 bits, and even if you did, all that would happen is that the
recorded minimum matching length would be some smaller number, which is not
very serious.

Thank you for reporting the issue, but I do not intend to take any action.
