   PCRE's "auto-possessification" optimization usually applies to character
   repeats at the end of a pattern (as well as internally). For example, the
   pattern "a\d+" is compiled as if it were "a\d++" because there is no point
   even considering the possibility of backtracking into the repeated digits. For
   DFA matching, this means that only one possible match is found. If you really
   do want multiple matches in such cases, either use an ungreedy repeat
   ("a\d+?") or set the PCRE_NO_AUTO_POSSESS option when compiling.
