https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D248452 --- Comment #2 from Kyle Evans <kevans@freebsd.org> --- My internal triage session below... I note that: Regular expression ".*(\w+)" is not a valid POSIX Extended regular expressi= on. \w is a GNU regex(3) extension that's short-hand for the POSIX-specified [[:alnum:]]. Prior to r363679, this expression would have been valid but incorrect, as it would match a literal 'w' rather than [[:alnum:]]. This is technically undefined behavior, and r363679 switched things up so that we h= ave two valid interpretations of that UB, either: 1.) Expression fails to compile, extraneous escape, OR 2.) Expression compiles and uses the GNU-extended behavior (libregex) This is favorable over #1 being 'Expression compiles and matches a literal = w'. I will fix this by soon (tonight, hopefully) introducing \w and \s, at leas= t, and linking gtest against libregex. --=20 You are receiving this mail because: You are the assignee for the bug.=
