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\ed+" is compiled as if it were "a\ed++" 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\ed+?") or set the PCRE_NO_AUTO_POSSESS option when compiling.

There are a number of features of PCRE regular expressions that are not
supported by the alternative matching algorithm. They are as follows:
