POSIX says it's UB: *+?{ The asterisk, plus-sign, question-mark, and left-brace shall be special except when used in a bracket expression. Any of the following uses produce undefined results: - If a left-brace is not part of a valid interval expression re_format(7) is free interpretation of the standard. FWIW, the best way is to fix your regular expressions. --=20 You are receiving this mail because: You are the assignee for the bug.=
