 set, and a match attempt fails when the current position is at a CRLF sequence,

+Anomalous effects can occur when CRLF is a valid newline sequence and explicit
+\er or \en escapes appear in the pattern. For example, the string "\er\enA"
+matches the unanchored pattern \enA but not [X\en]A. This happens because, in
+the first case, PCRE knows that the match must start with \en, and so it skips
+there before trying to match. In the second case, it has no knowledge about the 
+starting character, so it starts matching at the beginning of the string, and
+on failing, skips over the CRLF as described above. However, if the pattern is
+studied, the match succeeds, because then PCRE once again knows where to start.
