Public bug reported:

The 14.04/15.04 pcre version doesn't match some inputs with possessive
qualfiers:

$ echo '"a"'|pcregrep '("([^b"]*+(b.)?)*+")*+'
$

Earlier versions (10.04, 12.04):
$ echo '"a"'|pcregrep '("([^b"]*+(b.)?)*+")*+'
"a"
$

this is fixed with the following upstream commit (that applies cleanly
to the 15.04 pcre):
