--- Comment #1 from Philip Hazel <ph10@???> ---
This bug was present in both PCRE1 and PCRE2. It was provoked by a possessive
repeated character class other than * + or ? (your example isn't explicitly
possessive, being [0-9]{3}, but it got automatically possessified because the
next character cannot be a digit). I have fixed both PCRE1 and PCRE2 in the SVN
repository. It was a small oversight in the code. Here is the patch for PCRE1
8.40:

Thanks for the nice clear report.
