Bug ID: 2153 Summary: Compile error for pattern [[:ascii:]-] Product: PCRE Version: 10.23 (PCRE2) Hardware: x86 OS: Linux Status: NEW Severity: bug Priority: medium Component: Code Assignee: p...@hermes.cam.ac.uk Reporter: m...@michael-kaufmann.ch CC: pcre-dev@exim.org Since PCRE2 version 10.23, the pattern "[[:ascii:]-]" is not accepted anymore: "invalid range in character class" Perl accepts it without warning. I think the pattern should be accepted if the '-' is the last character in the sequence. The bug has been introduced with this change: 3. ... (g) A hyphen appearing immediately after a POSIX character class (for example /[[:ascii:]-z]/) now generates an error. Perl does accept this as a literal, but gives a warning, so it seems best to fail it in PCRE. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
