--- Comment #4 from [email protected] --- A commit references this bug: Author: kevans Date: Tue Aug 8 04:10:47 UTC 2017 New revision: 322211 URL: https://svnweb.freebsd.org/changeset/base/322211 Log: regex(3): Handle invalid {} constructs consistently and adjust tests Currently, regex(3) exhibits the following wrong behavior as demonstrated with sed: - echo "a{1,2,3}b" | sed -r "s/{/_/" (1) - echo "a{1,2,3}b" | sed "s/\}/_/" (2) - echo "a{1,2,3}b" | sed -r "s/{}/_/" (3) Cases (1) and (3) should throw errors but they actually succeed, and (2) throws an error when it should match the literal '}'. The correct behavior was decided by comparing to the behavior with the equivalent BRE (1)(3) or ERE (2) and consulting POSIX, along with some reasonable evaluation. Tests were also adjusted/added accordingly.
