$ 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): http://vcs.pcre.org/pcre?view=revision&revision=1478 https://lists.exim.org/lurker/message/20140527.131833.2fd7547c.html ** Affects: pcre3 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1456195 Title: Zero-minimum possessive groups does not match empty string To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcre3/+bug/1456195/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
