--- Begin Message ---Package: perl Version: 5.24.1-3 Severity: normal Tags: upstream Dear Maintainer, In some cases, some valid utf-8 chinese (or japanese Kanji) chars in a perl string makes perl die on "Malformed UTF-8" while matching a regexp. Here is the smallest programm (all in ascii, for safety) creating the problem. #!/usr/bin/perl use strict; use warnings; my $text = "[quant,_1,\x{55b6}\x{696d}\x{65e5},\x{55b6}\x{696d}\x{65e5}]\x{6bce}"; eval {$text =~ s{((?<!~)(?:~~)*)\[([A-Za-z#*]\w*)(?:,([^\]]+))?\]}{"$1%$2($3)"}eg; }; if ( $@ ) { die "Failed $@"; } else { print "Works, for now\n"; } The very same text, on the very same regexp, did not create problems on the previous (5.20.*, 5.22.*) versions of perl. We use that text, and that regexp, in production environment, using Debian stable, and everything is running fine. Beware : it *often* crashes. Not always. When you add entropy, you can get down to a crash out of two run of the program (use-ing some more stuff, printing, etc). This precise test script seems to crash everytime I use it on my developpement environment.
